Data stream clustering refers to the clustering of data that arrives continually such as financial transactions, multimedia data, or telephonic records. It is usually studied as a “Streaming Algorithm.” The purpose of Data Stream Clustering is to contract a good clustering stream using a small amount of time and memory.
Defensics is a generational fuzzer, which means it creates test cases based on a detailed model of the input data. The result: test cases that are very realistic but messed up in some way. This technique is highly effective in burrowing into different control paths in the target and revealing vulnerabilities. Subjectively speaking, the test cases have high quality. The disadvantage of generational fuzzing is that somebody has to create the data model for the inputs you are fuzzing.
Most modern software today has moved aggressively into using third-party open source dependencies to reduce duplication and accelerate development by using pre-existing code.
Virtual Private Networks, or VPNs, are not exactly a new technology. When I started my career in IT about 15 years ago, VPN tunnels were the standard way we connected remote offices by extending private networks over the public Internet. Recently, as workforces continue to decentralize due to the rise of Cloud Computing as well as the current pandemic, VPN has become an even hotter topic and is being marketed as a critical security solution.
Five worthy reads is a regular column on five noteworthy items we’ve discovered while researching trending and timeless topics. With the rising concern over cybersecurity in remote work, this week we explore the concept of the Zero Trust model in cybersecurity.
According to McAfee, Adaptive Threat Protection (ATP) is an endpoint security’s optional module that analyzes organizational content and decides action based on file rules, reputation, and reputation thresholds. According to another source, the ATP is a security model that monitors threats, improves cybersecurity risks changes, and evolves to meet the need for security systems that are integrated with IT for continuous deployment, as well as in hybrid environments and the virtual cloud.
Every organization needs to keep tabs on other players in the industry in order to stay competitive. It’s common for an organization to analyze a competitor’s website, perform secret shopping trips, and monitor a competitor’s marketing strategies. This type of competitive research is perfectly legal. But if an organization unlawfully obtains another company’s sensitive information, it is considered industrial espionage, which is illegal.
During the Investigation of a Suspicious Security Critical Event alarm, we discovered credentials had been dumped from the NTDS.dit, which is a database that stores Active Directory data, including password hashes for all users in the domain. By extracting these hashes, it’s possible for an attacker to use tools to gain access to user’s passwords, which allows them to act as any user on the domain, including the administrator.
Now that the sparkle and pop of the Fourth of July’s fireworks has subsided, it’s time for July’s open source vulnerabilities snapshot, your monthly overview of everything new in the always-evolving world of open source security.
