Questions or concerns? Feel free to reach out to us any time –
Google has announced that starting November 1, 2024, Chrome version 127 and higher will no longer trust new TLS server authentication certificates from Entrust and AffirmTrust. This decision follows a series of reported compliance failures, unfulfilled improvement commitments, and insufficient progress in addressing publicly disclosed incident reports observed over the past six years.
According to a blog post published by Google on June 27, website owners are advised to transition to a new publicly trusted Certification Authority (CA) before the deadline to avoid disruptions. Certification Authorities play a crucial role in securing encrypted connections between browsers and websites, adhering to stringent security and compliance standards. Google’s decision underscores the importance of these standards. More specifically, the Chrome Root Program Policy mandates that CA certificates must provide value that exceeds their risk.
“When these factors are considered in aggregate and against the inherent risk each publicly trusted CA poses to the Internet ecosystem, it is our opinion that Chrome’s continued trust in Entrust is no longer justified,” the blog post reads.
Background of Entrust and AffirmTrust
Entrust and AffirmTrust are established players in the field of digital security, providing critical infrastructure for secure communications over the internet. Entrust, founded in 1994, has a long history of offering identity-based security solutions, including public key infrastructure (PKI), digital certificates, and encryption technologies. The company has been a trusted certification authority (CA), ensuring the authenticity and security of digital transactions and communications. AffirmTrust, though newer, has also made significant contributions to the industry by providing a range of trusted digital certificates for securing online interactions. Both companies have played pivotal roles in enabling encrypted connections and ensuring data integrity and privacy across the web. However, recent compliance issues and security lapses have led to a reassessment of their roles as trusted entities in the digital ecosystem, culminating in Google’s decision to phase out trust in their certificates.
Impact on Website Operators
As a result of this update, after November 1, Chrome users visiting websites with certificates issued by Entrust or AffirmTrust will encounter security warnings. Website operators are encouraged to review their certificates and transition to a different CA to prevent service interruptions. This change will apply to Chrome on multiple platforms, including Windows, macOS, ChromeOS, Android, and Linux.
“The Entrust news is a sharp reminder of why it is so important for CAs to take their role as stewards of public trust very seriously. CAs have to hold themselves to the highest of standards, not only for the sake of their business but for all the people and businesses that depend on them,” commented Tim Callan, chief experience officer at Sectigo, an Arizona-based provider of certificate lifecycle management (CLM) solutions.
Background of the Decision
Over the past several years, publicly disclosed incident reports highlighted a pattern of concerning behaviors by Entrust that fall short of Google’s expectations. These behaviors have eroded confidence in their competence, reliability, and integrity as a publicly trusted CA owner. In response to these concerns and to preserve the integrity of the Web PKI ecosystem, Chrome will take definitive action.
Technical Details
TLS server authentication certificates validating to the following Entrust roots whose earliest Signed Certificate Timestamp (SCT) is dated after October 31, 2024, will no longer be trusted by default:
Certificates validating to these roots with SCTs on or before October 31, 2024, will be unaffected by this change. This approach attempts to minimize disruption to existing subscribers by using a recently announced Chrome feature to remove default trust based on the SCTs in certificates.
Actions for Website Operators
Website operators are strongly encouraged to transition to a new publicly trusted CA as soon as possible to avoid disruptions. Delaying action could result in service interruptions if certificates expire after October 31, 2024. While website operators could delay the impact by obtaining new TLS certificates from Entrust before November 1, 2024, this is only a temporary solution. Ultimately, they will need to secure certificates from other CAs included in the Chrome Root Store.
To determine if their website is affected, operators can use the Chrome Certificate Viewer. If the “Organization (O)” field under the “Issued By” heading contains “Entrust” or “AffirmTrust”, action is required.
Enterprise Considerations
For internal enterprise networks using Entrust certificates, administrators can override Chrome Root Store constraints by installing the corresponding root CA certificate as a locally trusted root on the platform Chrome is running. This ensures continued trust within enterprise environments.
Testing the Changes
Administrators and power users can simulate the effect of the SCTNotAfter distrust constraint by using a command-line flag in Chrome 128. This allows them to evaluate the impact of the changes before they take effect.
Industry Implications
The move by Google highlights the critical role CAs play in maintaining internet security. With the advent of a 90-day certificate lifecycle and the implications of quantum computing on the horizon, it is more important than ever for CAs and CLM providers to adhere to the highest standards and fully comply with CA/Browser Forum rules and baseline requirements.
Conclusion
Google’s decision to block Entrust certificates underscores the importance of maintaining high standards in the certification process. Website operators must act promptly to transition to new CAs to avoid disruptions. The integrity of the web ecosystem relies on the stringent adherence to security and compliance standards by all CAs.

How can Netizen help?
Phish Tale of the Week
Often times phishing campaigns, created by malicious actors, target users by utilizing social engineering. For example, in this email, the actors are appearing as CareCix. The message politely gives us an opportunity to sign up for some healthcare, even giving us a login page to speed up the process to signing in to our new account. It seems both urgent and genuine, so why shouldn’t we visit the link they sent us? Luckily, there’s plenty of reasons that point to this being a scam.
Here’s how we can tell not to click on this link:
The first warning sign for this email is the formatting. Immediately, it’s apparent that different text boxes in the email have different alignments and different sizes, as well as strange spacing. The “go to login page” button is a great example of this strange spacing: the white space above the button is significantly larger than the white space below. It’s important to be wary of small inconsistencies such as this as they can be key indicators that the sender of the email may not be who they seem.
The second warning signs in this email is the messaging. This message tries to create a sense of opportunity and urgency in order to get you to take action by using language such as “get started” and “this link is valid for 30 days.” Phishing and smishing scams commonly attempt to create a sense of urgency/confusion in their messages in order to get you to click their link without thinking about it first. Always be sure to thoroughly inspect the style and tone of all texts before following a link or other attachment sent through email.
The final warning sign for this email is the fact that we didn’t sign up for this healthcare. Receiving an email asking you to log into an account you didn’t create should always be a warning sign. Do not click on any “log in” or “sign up” button in any email you weren’t expecting, no matter how trustworthy it looks. With all of these 3 warning signs, it’s incredibly apparent that we are being phished.
General Recommendations:
A phishing attack will typically direct the user to click on a link where they will then be prompted to update personal information, such as a password, credit card, social security, or bank account information. A legitimate company already has this sensitive information and would not ask for it again, especially via your text messages.
Scrutinize your messages before clicking anything. Have you ordered anything recently? Does this order number match the one I already have? Did the message come from a store you don’t usually order supplies from or a service you don’t use? If so, it’s probably a phishing attempt.
Verify that the sender is actually from the company sending the message.
Did you receive a message from someone you don’t recognize? Are they asking you to sign into a website to give Personally Identifiable Information (PII) such as credit card numbers, social security number, etc. A legitimate company will never ask for PII via instant message or email.
Do not give out personal or company information over the internet.
Do not click on unrecognized links or attachments. If you do proceed, verify that the URL is the correct one for the company/service and it has the proper security in place, such as HTTPS.
Many phishing messages pose a sense of urgency or even aggressiveness to prompt a form of intimidation. Any email requesting immediate action should be vetted thoroughly to determine whether or not it is a scam. Also, beware of messages that seek to tempt users into opening an attachment or visiting a link. For example, an attachment titled “Fix your account now” may draw the question “What is wrong with my account?” and prompt you to click a suspicious link.
Cybersecurity Brief
In this month’s Cybersecurity Brief:
P2PInfect Botnet Evolves: New Miner and Ransomware Payloads Detected
The notorious P2PInfect botnet, known for targeting misconfigured Redis servers, has evolved into a formidable threat with the addition of ransomware and cryptocurrency miners. This transformation signifies a shift from a seemingly dormant botnet to a financially motivated operation.
Recent updates have significantly increased the threat level posed by P2PInfect. Initially perceived as a dormant threat, the botnet now deploys crypto miners, ransomware payloads, and rootkit elements. This development highlights the malware author’s intent to profit from illicit access and expand their network. Additionally, P2PInfect has been updated to target MIPS and ARM architectures, broadening its scope and potential impact.
P2PInfect primarily spreads by exploiting the replication feature of Redis servers, transforming victim systems into follower nodes under the attacker’s control. This allows the attacker to execute arbitrary commands on infected systems. The botnet also includes a feature to scan the internet for additional vulnerable servers and incorporates an SSH password sprayer module to gain access using common passwords.
The behavioral changes in P2PInfect are noteworthy. The botnet now drops miner and ransomware payloads, encrypting files with specific extensions and demanding a ransom of 1 XMR (approximately $165). Furthermore, a new usermode rootkit uses the LD_PRELOAD environment variable to hide malicious processes and files from security tools, a technique similar to those used by other cryptojacking groups.
Given the nature of targeted servers, which often store ephemeral in-memory data, the ransomware’s impact is limited. Therefore, the botnet likely sees more profit from its crypto miner due to its extensive use of system resources. Evidence suggests that P2PInfect might be a botnet-for-hire service, deploying other attackers’ payloads in exchange for payment. This theory is supported by the different wallet addresses used for miner and ransomware processes.
To secure its foothold, P2PInfect takes several defensive measures. It changes user passwords, restarts SSH services with root permissions, and performs privilege escalation to prevent other attackers from targeting the same servers.
In conclusion, the P2PInfect botnet represents a significant threat in the cybersecurity landscape, especially with its recent updates. Organizations must remain vigilant and employ robust security measures to protect against such sophisticated attacks. Regularly patching systems, monitoring for unusual activities, and implementing strong access controls are crucial steps in defending against botnet infections and their evolving payloads.
Lurie Children’s Hospital Says 791,000 Impacted by Ransomware Attack
Ann & Robert H. Lurie Children’s Hospital of Chicago has announced that a recent ransomware attack has compromised the personal and health information of 791,000 individuals. The hospital took many of its systems offline in late January in response to the cyberattack, which led to limited access to medical records, disruptions to a patient portal, and hampered communications.
An investigation revealed that cybercriminals had access to Lurie Children’s systems between January 26 and January 31, 2024. A wide range of information was compromised, including names, addresses, dates of birth, dates of service, driver’s license numbers, Social Security numbers, email addresses, phone numbers, health claims information, medical conditions or diagnoses, medical record numbers, medical treatments, and prescription information.
Although the hospital did not explicitly state that it was targeted by a ransomware group, it confirmed in a data breach notification on its website that it refused to pay a ransom. “Experts have advised that making a payment to cybercriminals does not guarantee the deletion or retrieval of data that has been taken. Once our investigation team identified an amount of data that was impacted by the cybercriminals, we worked closely with law enforcement to retrieve that data,” Lurie Children’s said.
The Rhysida ransomware group, which claimed responsibility for the attack, has stated on its website that the data stolen from the hospital has been sold, indicating that a ransom was not paid. The cybercriminals allege they stole 600 GB of data from the organization.
A notice published by the Maine Attorney General’s office on Thursday reveals that the incident has affected more than 791,000 people. Impacted individuals are being notified and offered 24 months of identity and fraud protection services at no cost.

The Cybersecurity and Infrastructure Security Agency (CISA), in collaboration with the FBI, New Zealand’s Government Communications Security Bureau (GCSB), New Zealand’s Computer Emergency Response Team (CERT-NZ), and the Canadian Centre for Cyber Security (CCCS), has published a comprehensive report on modern network access security approaches. This report, released on June 18, 2024, addresses the vulnerabilities and risks associated with traditional VPN solutions and advocates for more secure alternatives.
Overview
CISA has frequently identified incidents involving the compromise of virtual private network (VPN) solutions, often exploited by cybercriminals and nation-state actors. With over 22 Known Exploited Vulnerabilities (KEVs) associated with VPNs, there is a pressing need to transition to modern network access security solutions. The increasing shift of services to the cloud further emphasizes the importance of adopting Secure Access Service Edge (SASE) over traditional on-premises security stacks. This report aims to guide organizations in enhancing their security postures by integrating more secure, cloud-based solutions that align with zero trust (ZT) principles.
Remote Access and VPN Limitations
While VPNs provide encrypted tunnels for remote access to corporate networks, they pose several security risks. These include vulnerabilities inherent in network design, such as IP address spoofing and DNS spoofing, as well as the complexity of implementation and misconfiguration issues. Additionally, the integration of third-party access and poor cyber hygiene practices can further expose networks to threats. Traditional VPNs often lack the granular access control required to enforce zero trust principles effectively.
Impact
Exploited vulnerabilities in VPN systems can lead to widespread access across enterprise networks, resulting in significant operational disruptions and data breaches. Recent examples include:
CVE-2023-46805 and CVE-2024-21887: Affecting Ivanti Connect Secure (ICS) VPNs, these vulnerabilities allowed attackers to reverse tunnel from the ICS VPN appliance, modify JavaScript files used by the Web SSL VPN component, and compromise credentials.
CVE-2023-4966 (Citrix Bleed): Affecting Citrix NetScaler web application delivery controllers and NetScaler Gateway appliances, this vulnerability allowed threat actors to bypass password requirements and multifactor authentication (MFA), leading to the hijacking of legitimate user sessions and subsequent credential harvesting.
These vulnerabilities underscore the critical need for organizations to move beyond traditional VPN solutions to more advanced, secure access technologies.
Solutions
To address these challenges, CISA recommends several modern network access security solutions:
Zero Trust (ZT): Defined by the National Institute of Standards and Technology (NIST) in Special Publication 800-207, zero trust is a security model that requires continuous verification of user, device, and application authenticity. It enforces least privilege access and continuous reauthentication, operating under the assumption that no user or asset should be implicitly trusted.
Secure Service Edge (SSE): A collection of cloud security capabilities that enable safe browsing, secure access to software as a service (SaaS) applications, and validation of users accessing network data. SSE integrates security and access control into a single platform, encompassing Zero Trust Network Access (ZTNA), Cloud Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), and Firewall-as-a-Service (FWaaS).
Secure Access Service Edge (SASE): A cloud architecture that combines network and security as a service capabilities, including software-defined wide area networking (SD-WAN), SWG, CASB, next-generation firewall (NGFW), and ZTNA. SASE provides comprehensive security and network management from a unified cloud-based platform.
Hardware-Enforced Network Segmentation: Adds a layer of hardware protection to enhance defense-in-depth strategies, using technologies like unidirectional gateways and data diodes to ensure robust network segmentation.
Best Practices
To effectively transition to modern network access security solutions, CISA and its partner organizations recommend the following best practices:
Implement Centralized Management Solutions: Centralized management allows system administrators to control remote access to applications and servers, manage privileged access, and simplify network control. This approach is critical for modern network defenses due to the underlying issue that no VPN can guarantee absolute security.
Enforce Network Segmentation: Implement strict network segmentation, denying all connections to operational technology (OT) networks by default unless explicitly allowed. Use unidirectional technologies for the most consequential systems to ensure strong protection against cyber threats.
Automate Security Orchestration, Automation, and Response (SOAR): Implement automated responses to certain security events to enhance incident detection and response capabilities.
Maintain and Regularly Drill Cybersecurity Incident Response Plans: Develop, update, and regularly drill IT and OT cybersecurity incident response plans for both common and organizationally specific scenarios. Update these plans based on lessons learned from exercises and drills.

Identity and Access Management (IAM) is essential for ensuring that only authorized individuals have access to sensitive information, helping organizations maintain security, compliance, and efficiency. By centralizing control over user identities and access rights, IAM streamlines the creation, maintenance, and deletion of user identities while enforcing precise access controls.
What IAM Is and What It Does
In today’s work environment, employees need access to various resources like applications, files, and data, regardless of their location. Traditionally, most employees worked on-site, with resources protected by a firewall. Once logged in on-site, employees could access the necessary tools and data.
Now, with hybrid work becoming more common, employees require secure access to company resources whether they’re on-site or remote. IAM addresses this need by controlling what users can and cannot access, ensuring sensitive data and functions are only accessible to those who need them.
IAM ensures secure access to company resources such as emails, databases, and applications for verified users, ideally with minimal interference. The objective is to manage access so that authorized individuals can perform their jobs effectively while unauthorized access is denied.
This need for secure access extends beyond employees on company devices; it includes contractors, vendors, business partners, and individuals using personal devices. IAM guarantees that each person with access has the correct level of access at the appropriate time and on the right device. Given its role in cybersecurity, IAM is an integral part of modern IT.
An IAM system allows organizations to quickly and accurately verify a person’s identity and ensure they have the necessary permissions for the requested resource during each access attempt.
How IAM Works
IAM involves two main components: identity management and access management.
Identity Management
Identity management verifies login attempts against an identity management database, which is continually updated to reflect changes as people join or leave the organization, or as their roles and projects evolve.
The identity management database stores information such as employee names, job titles, managers, direct reports, mobile phone numbers, and personal email addresses. Matching login information like usernames and passwords with this database is known as authentication.
For enhanced security, many organizations use multifactor authentication (MFA). MFA adds an extra step to the login process, requiring users to verify their identity using an alternate method, such as a code sent to a mobile phone. This makes the system more secure than relying on a username and password alone.
Access Management
Access management controls which resources a user can access after their identity is authenticated. Organizations grant varying levels of access based on factors like job title, tenure, security clearance, and specific projects.
Authorization, the process of granting access to resources, ensures that authentication and authorization are handled correctly and securely during each access attempt.
The Importance of IAM for Organizations
IAM is vital because it helps balance security and accessibility. It enables IT departments to set controls that grant secure access to employees and devices while making it difficult for unauthorized users to gain entry.
Cybercriminals are constantly refining their techniques. Phishing emails, for instance, are a common method used to hack and breach data. Without IAM, managing who has access to an organization’s systems is challenging. Breaches can proliferate because it’s difficult to monitor access and revoke it from compromised users.
While perfect security is unattainable, IAM solutions can prevent and minimize the impact of attacks. Many IAM systems are AI-enabled, capable of detecting and stopping attacks before they escalate.
Benefits of IAM Systems
Implementing an effective IAM system brings numerous advantages.
IAM ensures that the right people have the right access. By creating and enforcing centralized rules and access privileges, IAM systems ensure users can access necessary resources without being able to reach sensitive information they don’t need. Role-based access control (RBAC) allows for scalable restriction of access based on job roles.
IAM also supports productivity. While security is crucial, so are productivity and user experience. Overly complex security systems can hinder productivity. IAM tools like single sign-on (SSO) and unified user profiles provide secure access to multiple channels, reducing the need for multiple logins and enhancing user convenience.
IAM significantly reduces the risk of data breaches. Tools like MFA, passwordless authentication, and SSO enable users to verify their identities with more than just a username and password, which can be forgotten, shared, or hacked. IAM solutions add an extra layer of security to the login process, making it harder for unauthorized users to gain access.
Data encryption is another benefit. IAM systems often include encryption tools that protect sensitive information during transmission. Features like Conditional Access allow IT administrators to set conditions (such as device, location, or real-time risk information) for access, ensuring data remains secure even in the event of a breach.
IAM also decreases manual workload for IT departments. Automating tasks such as password resets, account unlocking, and access log monitoring saves time and effort. This allows IT teams to focus on strategic initiatives like implementing a Zero Trust security framework, which relies on verifying explicitly, using least privileged access, and assuming breach.
IAM enhances collaboration and efficiency. It facilitates secure, seamless collaboration between employees, vendors, contractors, and suppliers. Automated workflows speed up permission processes for role changes and new hires, reducing onboarding time.
IAM and Compliance Regulations
Managing access manually is time-consuming and labor-intensive. IAM systems automate this process, making auditing and reporting faster and more straightforward. They enable organizations to demonstrate proper governance of sensitive data access during audits, which is required by many contracts and laws.
Many regulations, laws, and contracts require data access governance and privacy management. IAM solutions verify and manage identities, detect suspicious activity, and report incidents, all essential for compliance. Standards like GDPR in Europe and HIPAA and the Sarbanes-Oxley Act in the U.S. mandate strict security measures. A robust IAM system simplifies compliance with these requirements.
IAM Technologies and Tools
IAM solutions integrate with various technologies and tools to enable secure authentication and authorization at an enterprise scale:
Security Assertion Markup Language (SAML): SAML enables SSO by notifying applications that a user is verified after authentication. SAML’s cross-platform capability makes secure access possible in diverse contexts.
OpenID Connect (OIDC): OIDC adds identity to OAuth 2.0, sending encrypted tokens with user information between identity and service providers. These tokens, containing data like names and email addresses, facilitate authentication for apps and services.
System for Cross-Domain Identity Management (SCIM): SCIM standardizes user identity management across multiple apps and providers, ensuring users have access without creating separate accounts.
Implementing IAM
Implementing an IAM system requires thorough planning. Start by calculating the number of users needing access and listing the solutions, devices, applications, and services the organization uses. These lists help compare IAM solutions for compatibility with existing IT setups.
Next, map out the roles and situations the IAM system must accommodate. This framework will form the basis of the IAM documentation.
Consider the solution’s long-term roadmap. As the organization grows, its IAM needs will evolve. Planning for this growth ensures the IAM solution aligns with business goals and is set up for long-term success.
IAM Solutions
IAM solutions can be standalone systems, managed identity services, or cloud-based offerings (Identity as a Service – IDaaS). Red Hat Enterprise Linux, for example, provides comprehensive IAM capabilities that integrate with various third-party solutions.
Selecting the right IAM solution is crucial for effective implementation and long-term success. Ensure the solution integrates seamlessly with existing systems and supports a wide range of environments, including on-premise, cloud, and hybrid setups. This ensures a smooth transition and avoids operational disruptions.
Choose a solution that can grow with your organization. As your business expands, your IAM system should accommodate an increasing number of users and access requests. Look for advanced security features like MFA, PAM, and encryption, and ensure the solution supports compliance with relevant regulations and standards.

In the realm of modern military operations, the ability to securely and reliably communicate classified information is paramount. The Secret Internet Protocol Router Network (SIPRNet) was developed to address this need, providing a robust platform for transmitting sensitive data while avoiding the vulnerabilities of public internet systems. This article delves into the evolution, significance, and security measures of SIPRNet, highlighting its indispensable role in U.S. national defense.
The Evolution of Secure Military Networks
The origins of secure military communication networks trace back to the Defense Information Systems Network (DISN), which has been operational for over 40 years. DISN was established to provide secure telecommunications services, including data, video, and phone communications, to all branches of the U.S. military and other key government entities such as the White House.
DISN supports several specialized networks designed to handle various levels of classified information:
Non-Classified Internet Protocol Router Network (NIPRNet): This network facilitates the transmission of unclassified but sensitive information, ensuring privacy and security for defense agencies and contractors.
Secret Internet Protocol Router Network (SIPRNet): A secure network for transmitting information classified at the SECRET level.
Joint Worldwide Intelligence Communications System (JWICS): An even more secure network handling TOP SECRET information.
The Backbone of Classified Communications
SIPRNet is a global network of interconnected computer systems used by the Department of Defense (DoD) and the Department of State. It is designed to handle and protect classified information, supporting services like HTML document access, email, and file transfers. Unlike the public internet, SIPRNet operates in a completely secure environment, isolated from public networks to prevent unauthorized access.
The development of SIPRNet was driven by the need to replace the outdated DSNET1 portion of DISN. The newer network infrastructure offered a more secure and efficient way to manage and transmit SECRET-level information, utilizing familiar internet protocols and interfaces but within a protected framework.
Security Measures and Compliance
