The National Institute of Standards and Technology (NIST) provides guidelines on digital forensics, which include methodologies for properly collecting, examining, and analyzing digital evidence. This framework helps ensure that digital evidence is handled in a manner that preserves its integrity and maintains its admissibility in legal proceedings:

• Digital Forensics Process: This process involves steps to ensure that data collected from digital sources can be used reliably in investigations and court cases, addressing chain-of-custody issues, proper evidence handling, and detailed documentation of forensic procedures.

In ArubaOS firewall policies, using network aliases allows administrators to manage groups of IP addresses more efficiently. By associating multiple IPs with a single alias, any changes made to the alias (like adding or removing IP addresses) are automatically reflected in all firewall rules that reference that alias. This significantly simplifies the management of complex rulesets and ensures consistency across security policies, reducing administrative overhead and minimizing the risk of errors.

The ArubaOS firewall is a stateful firewall, meaning that it can track the state of active sessions and can make decisions based on the context of the traffic. This stateful inspection capability allows it to automatically allow return traffic for sessions that it has permitted, thereby enabling seamless two-way communication for authorized users while maintaining the security posture of the network.References:

Control Plane Policing (CoPP) on Aruba switches is used to mitigate Denial of Service (DoS) attacks on the switch. CoPP allows network administrators to restrict the impact of control plane traffic on the switch's CPU, thereby protecting network stability and integrity. By setting rate limits and specifying allowed traffic types, administrators can prevent malicious or malformed packets from overwhelming the switch's control plane, which could otherwise lead to a DoS condition and potentially disrupt network operations. This use case of CoPP is detailed in Aruba's network management documentation, where best practices and configurations to protect against DoS attacks are discussed.
