ExplanationExplanationDevSecOps (development, security, and operations) is a concept used in recent years to describe how to movesecurity activities to the start of the development life cycle and have built-in security practices in the continuousintegration/continuous deployment (CI/CD) pipeline. Thus minimizing vulnerabilities and bringing security closerto IT and business objectives.Three key things make a real DevSecOps environment:+ Security testing is done by the development team.+ Issues found during that testing is managed by the development team.+ Fixing those issues stays within the development team.

 A SYN flood is a type of denial-of-service (DoS) attack that exploits the TCP three-way handshake process to exhaust the resources of a target server. The attacker sends a large number of SYN packets to the target server, each with a spoofed source IP address. The target server allocates resources for each incoming SYN packet and responds with a SYN-ACK packet to the spoofed address. However, the spoofed address never sends back the final ACK packet to complete the connection, leaving the target server with many half-open connections that eventually fill up its connection table. This prevents the target server from accepting new legitimate connections and causes service disruption123 References: 1: Implementing and Operating Cisco Security Core Technologies (SCOR) v1.0 course overview 2: SYN Flood Explained. How to Prevent this Attack from Taking over your … 3: What is a SYN flood attack? | Cloudflare

ExplanationExplanationStorm control prevents traffic on a LAN from being disrupted by a broadcast, multicast, or unicast storm on one of the physical interfaces. A LAN storm occurs when packets flood the LAN, creating excessive traffic and degrading network performance. Errors in the protocol-stack implementation, mistakes in network configurations, or users issuing a denial-of-service attack can cause a storm.By using the “storm-control broadcast level [falling-threshold]” we can limit the broadcast traffic on the switch.
