Another way of testing firewall rules with Nmap is to add results from other network security tools. For example, begin by running a protocol analyzer, such astcpdumporWireshark, to collect traffic samples. These analyzers capture packets, and by carefully looking at the headers, you can deter...
You should be thorough with various security principles and protocols, such as access control, confidentiality, privacy, etc., to build less vulnerable systems. 5. Understanding of Different Cyber Threats You must have technical know-how about different cyber threats like DDoS Attacks, Malware threats...

At the same time, it may be used as a means to detect false positives, i.e. innocuous resources detected as malicious by one or more scanners. IntelMQ - IntelMQ is a solution for CERTs for collecting and processing security feeds, pastebins, tweets using a message queue protocol. It's...
You can useweb application firewallsto detect anomalies in the incoming traffic and block potentially malicious traffic as it comes. But to fix robust security defenses, it’s crucial to understand session hijacking in detail, its types, and the tools that attackers might use to penetrate user ac...
with privileged access can easily compromise systems. Such attacks are usually difficult to detect and protect against since the employees do not need to infiltrate the network. Additionally, some employees can unintentionally infect the network with malware when they plug in USB devices with malware....
Monitoring network traffic with a NetFlow analyzer enables IT teams to capture, analyze, and visualize flow data, helping them track bandwidth usage and detect inefficiencies across the network. Here’s a breakdown of the key components in this process: Flow exporter A network device, such as a...
As you can see in wireshark, IP protocol data in the packet (also called IP header) has many fields, most important are "Source", "Destination". The "Differentiated Services Field" (includes DSCP bits) is used to prioritise VoIP traffic in IP routers. Tasks with this file: See what ...
By creating a DDoS response plan, you'll have a roadmap for actions during an attack. This plan should detail how to detect attacks, respond, and recover post-attack. Also, ensure continuous communication with a business continuity plan during a DDoS assault. By creating a DDoS response plan...
