In today’s complex network infrastructure comprised of diverse resources, devices, and users, port scans represent a significant amount of network traffic. Crackers and hackers alike use port scanners to discover port vulnerabilities that can become attack vectors to malicious outcomes. In this post, we discuss the fundamentals of port scanning, and why you need to deploy an effective port scanner software on your network right now.
A common component of modern cybersecurity infrastructure, a cloud access security broker (CASB) is technology that provides monitoring and mitigates risks from employee use of cloud services. CASBs were initially developed to fill a gap in cloud security visibility left behind by traditional firewalls, next-generation firewalls, and early secure web gateways, which struggled to identify instances of the unapproved use of cloud services, otherwise known as shadow IT or rogue IT.
In times long gone, disgruntled former employees could only do so much damage to your company, and relatively little at all to your data security. In the fast-moving world of the 21st century, however, it’s a different story. Costly data breaches and devastating thefts have been undertaken in recent years by dissatisfied staff members released from their job duties.
This blog provides an overview of the situation surrounding the release of the source code, and supplementary 'injection' files, for the Android banking trojan 'Cerberus'.
This blog summarizes the findings of an investigation into the current status of the Brazilian threat group known as 'Prilex' who came to prominence in late 2017 and early 2018 for their ATM jackpotting and point-of-sale (POS) terminal attacks. Whilst the group were believed to have been active since 2014, a distinct absence of 'chatter' and reporting of their activity since 2018 seemingly suggested that the group had ceased operations.
At the convergence of digital transformation, an industry-wide focus on SASE, and the effects of the continuing COVID-19 pandemic, there are key forces that security practitioners need to be aware of and operate within. This is the first blog in a series of three detailing these forces and how security leaders and practitioners can adapt to them in a digitally transforming, SASE-enabled world. This blog covers the forces of Business Strategy and Information Technology Operations.
About a year ago, a friend of mine decided to build an EVM (Ethereum Virtual Machine) assembler in Rust. After some prodding from him, I began to help by writing unit tests. At the time, I knew very little about operating systems and started to read about lexical and symbolical analyzers. I was quickly in way over my head. What I did retain, however, was a newfound appreciation for the OS as a whole. So, when he started raving about eBPF, I knew I was in for a treat.
