PCI DSS 4.0 encourages the implementation of anti-phishing controls like DMARC! This highlights and reinforces the importance of preventative measures against email fraud, domain spoofing, and phishing in the financial space. While not a mandate or a requirement for PCI DSS compliance, DMARC and supporting email authentication technologies like SPF and DKIM play a pivotal role in protecting domain names against misuse.  Organizations can sign up for a DMARC analyzer trial to simplify their DMARC implementation, without the need for technical expertise. With more than 94% of organizations falling victim to phishing, this is the cue for businesses of all sizes to strengthen domain security and prevent the next big cyber attack. Many organizations turn to email authentication management solutions like PowerDMARC to simplify implementation, monitor authentication, and ensure continuous protection. On the flip side, it also presents a golden opportunity for MSPs to sell DMARC to th...

The PCI DSS landscape is evolving rapidly. With the Q1 2025 deadline looming ever larger, businesses are scrambling to meet the stringent new requirements of PCI DSS v4.0. Two sections in particular, 6.4.3 and 11.6.1, are troublesome as they demand that organizations rigorously monitor and manage payment page scripts and use a robust change detection mechanism. With the deadline fast approaching and the consequences of non-compliance so severe, there is no room for complacency, so, in this article, we look at the best way to meet these complex coding requirements. PCI DSS v4: Understanding Requirements 6.4.3 and 11.6.1 These changes to PCI DSS in v4.0 acknowledge the urgent need to tighten client-side security in the face of pervasive supply-chain threats. They call for beefed-up payment page security to keep customers' sensitive payment details safe from malicious script injection attacks: 6.4.3: To meet this requirement your organization needs to monitor and manage all payment ...

Data security is reinventing itself. As new data security posture management solutions come to market, organizations are increasingly recognizing the opportunity to provide evidence-based security that proves how their data is being protected. But what exactly is data security posture, and how do you manage it?  Data security posture management  (DSPM) became mainstream following the publication of Gartner® Cool Vendors™ in Data Security—Secure and Accelerate Advanced Use Cases. In that  report , Gartner1 seems to have kicked off the popular use of the data security posture management term and massive investment in this space by every VC. Since that report, Gartner has identified at least 16 DSPM vendors, including Symmetry Systems. What is Data Security Posture? There certainly is a lot being marketed and published about data security posture management solutions themselves, but we first wanted to dig into what is data security posture?  Symmetry Systems define...

If you invite guest users into your Entra ID tenant, you may be opening yourself up to a surprising risk.  A gap in access control in Microsoft Entra's subscription handling is allowing guest users to create and transfer subscriptions into the tenant they are invited into, while maintaining full ownership of them.  All the guest user needs are the permissions to create subscriptions in their home tenant, and an invitation as a guest user into an external tenant. Once inside, the guest user can create subscriptions in their home tenant, transfer them into the external tenant, and retain full ownership rights. This stealthy privilege escalation tactic allows a guest user to gain a privileged foothold in an environment where they should only have limited access. Many organizations treat guest accounts as low-risk based on their temporary, limited access, but this behavior, which works as designed, opens the door to known attack paths and lateral movement within the resource t...

Protecting customer data is critical for any business accepting online payment information. The Payment Card Industry Data Security Standard (PCI DSS), created by leading credit card companies, establishes best practices for protecting consumers' information. By adhering to these standards, businesses can ensure that their customer's personal and financial information is secure.  The PCI DSS security standards apply to any business that processes, stores, or transmits credit card information. Failure to comply with the PCI DSS can result in costly fines and penalties from credit card companies. It can also lead to a loss of customer trust, which can be devastating for any business. PCI DSS 4.0 was released in March 2022 and will replace the current PCI DSS 3.2.1 standard in March 2025. That provides a three-year transition period for organizations to be compliant with 4.0. The latest version of the standard will bring a new focus to an overlooked yet critically important ar...

Complying with cyber regulations forms a significant portion of the CISO's responsibility. Compliance is, in fact, one of the major drivers in the purchase and implementation of new security products. But regulations come in multiple different colors and shapes – some are tailored to a specific vertical, while others are industry-agnostic. Some bare explicit consequences for failing to comply, while others have a more guidance-like nature. The Comprehensive Security Guide (download here) , for the first time, provides security executives with a single document that gathers standardized and easy to use templates of all main compliance frameworks: PCI-DSS, HIPAA, NIST Cyber Security Framework and GDPR. Employing an independent auditor is the common practice to ensure one complies with the desired regulation. However, before having an external auditor excavating through the organizations' security stack internals, it makes sense for the security stakeholders to independ...
