The Nmap community reports that the tool, which anyone can get for free, is downloaded several thousand times every week.To read this article in full, please click here READ MORE HERE…

4 lessons learned from the Atlassian network outage

Last month, software tools vendor Atlassian suffered a major network outage that lasted two weeks and affected more than 400 of their over 200,000 customers. The outage took down several of their products, including Jira, Confluence, Atlassian Access, Opsgenie, and Statuspage. While only a few customers were affected for the full two weeks, the outage was significant in terms of the depth of problems uncovered by the company’s engineers and the lengths they had to go to find and fix the problems.The outage was the result of a series of unfortunate internal errors by Atlassian’s own staff, and not the result of a cyberattack or malware. In the end, no customer lost more than a few minutes’ worth of data transactions, and the vast majority of customers didn’t see any downtime whatsoever.To read this article in full, please click here READ MORE HERE…

What is NAC and why is it important for network security?

Network Access Control (NAC) is a cybersecurity technique that prevents unauthorized users and devices from entering private networks and accessing sensitive resources. Also known as Network Admission Control, NAC first gained a foothold in the enterprise in the mid-to-late 2000s as a way to manage endpoints through basic scan-and-block techniques.As knowledge workers became increasingly mobile, and as BYOD initiatives spread across organizations, NAC solutions evolved to not only authenticate users, but also to manage endpoints and enforce policies.How NAC works
NAC tools detect all devices on the network and provide visibility into those devices. NAC software prevents unauthorized users from entering the network and enforces policies on endpoints to ensure devices comply with network security policies. NAC solutions will, for instance, make sure that the endpoint has up-to-date antivirus and anti-malware protections.To read this article in full, please click here READ MORE HERE…
