As IT pros already know, when we speak of ports, we mean the 16-bit virtual ports used when interconnecting systems i.e. during communication over protocols such as TCP or UDP and not physical connections on the system such as USB, HDMI etc. See the OSI model and list of port numbers and their assigned function if not an IT pro. Port 80 is commonly used for HTTP activity, for example, and many applications communicate using assigned default ports.
In many jurisdictions, there is a legislative or accounting requirement to store data for a minimum of five years. Easier said than done. That’s why multiple data backups are necessary.
Scanning ports is very popular among cybercriminals. It’s often their first step of reconnaissance to discover services they can exploit and systems they can break into as they try to steal or destroy sensitive data. Two recent examples of major breaches illustrate just how handy port scanning is to threat actors:
Despite being an essential piece of the Sysadmin toolbox, Network performance management (NPM) can be a bit of a mystery for many IT professionals.

Windows event logs are a tool that every cybersecurity and IT professional should have in his or her arsenal. They can be used locally for troubleshooting or centralized for network awareness. When utilized centrally, powerful software known as a Security Information Event Management (SIEM) can be utilized to parse and search log files. But what if you are working locally? Is there an efficient method to do the same? You will find the answer to these questions lies in Microsoft’s most powerful tool belt, Microsoft PowerShell.
The World Wide Web’s 30th birthday came and went this week, and though there was much to celebrate—just look how far we’ve gone since the days of America Online CDs and Yahoo! chat rooms— it also seems like the problems the Internet causes are beginning to outweigh the problems it solves.
Many companies that never dreamed they’d be developing their own software are having to “roll their own.” Sometimes it’s an internal-use-only, as a custom layer over an existing platform like Salesforce, sometimes as a product they’re selling.
