Week 6 System Hardening and Network

 Access Control Lists (ACLs) are a set of rules that can control incoming or outgoing traffic in a network. They are typically used to selectively admit or reject inbound traffic, thereby preventing access to a network or specific resources on a network.

 

ACLs can be implemented in routers and switches, and they work by examining the source and destination IP addresses, protocols, and network traffic ports. Based on the rules defined in the ACL, the router or switch can allow or deny traffic.

 

ACLs are a valuable tool for controlling traffic in a network, but there are better ways to do so. For example, firewalls can provide more granular control over network traffic by examining the contents of packets and applying more complex rules. Additionally, intrusion detection and prevention systems can detect and block malicious traffic.

In summary, ACLs are a valuable tool for controlling network traffic, but there are better ways. The best approach depends on the specific needs of the network and the resources available to implement security measures.

System Hardening and Network week 3

  There are several tools available for identifying systems present on a network before conducting vulnerability tests .  One such tool is the Nessus Vulnerability Scanner. Nessus is a widely used vulnerability scanner that can identify IT assets, web applications, and cloud infrastructure vulnerabilities . It is designed to assess the modern attack surface and can be used to extend beyond traditional IT assets. Nessus is trusted by thousands of organizations worldwide and is considered the gold standard for vulnerability assessment. I like this tool because it helps network administrators access organizational threats .

System Hardening Week 2

  The  Application layer  is the seventh and highest layer of the OSI and TCP/IP models. It specifies the shared communication protocols and interface methods hosts use in a communications network. The protocols in the Application layer are responsible for providing services to the user, such as file transfer, email, and web browsing.

  A Virtual Private Network (VPN) enables secure remote access to corporate resources. Critical aspects of VPN policies include: Connection Procedures: Employees with VPN privileges must ensure unauthorized users are not allowed access. VPNs should enforce robust authentication methods and secure data transmission. Security Measures: VPN users must comply with information security policies, use up-to-date anti-virus software, and configure their equipment correctly. Impact Assessment: Microsoft recently faced DDoS attacks that disrupted services like Outlook and OneDrive. While DDoS attacks mainly cause inconvenience, they can disturb global commerce if they affect critical services.
