Physical Network Audit
NTIPL boosts of highly trained, skilled and technologically advanced auditors which can help you in going through each and every step of the physical Network Audit.
A detailed network audit is recommended for anybody and everybody who is managing a network. As a network engineer or manager, one should be aware of the network layout, inventory, top talkers, and traffic pattern into his network. This would not only make the troubleshooting easy but would also reduce the Mean-Time-to-Repair (MTTR) to a great extent. The main points that have to be covered in the auditing are:
- Network topology and physical infrastructure documentation in Visio or similar electronic format.
- Network addresses and names are assigned in a structured manner and are well.
- Network wiring is installed in a structured manner and is well labeled.
- Network wiring between communications closets and end stations is generally no more than 100 m.
- Network security for basic security
- Inventory of all routers and switches.
- Security of physical location
- Configuration – Check your configurations regularly and do keep a backup of all of them.
- Passwords for all equipment – Maintain a database of all credentials at a secure location.
- Special redundancy measures (HSRP, VRRP etc.)
- Link information
- Traffic volume (bytes)
- Identify WAN links that terminate in routers outside the AS.
- Points of Contact at external AS.
- Method of route sharing with the external AS (static routes, BGP, IGP, etc.).
- WAN link physical clocking rates.
- CIR for WAN circuits
- Document physical interconnecting media for each segment (10BT, Fiber, etc.)
- Identify locations of major servers.
- Locate network management stations.
- Identify and locate all firewalls and respective topologies
- Contact information at each remote site (primary and secondary contact person name, email address, and phone number).
- Document the services and clients that exist at each site and their relative importance to the business.
- Document the charges for each WAN circuit.
