Cyber Security Through Technology Risk Management

In remote management, upstream or downstream interfaces of a network device are configured to accept the console connection such Telnet or SSH. The management traffic flows along with other transiting data traffic thru same interface.

Proxy ARP ( Address Resolution Protocol ) is a technique by which a intermediate network device like router replies to ARP request for a given IP address that is not part of local network.  The router acts as a proxy for the destination device to which the host wants to communicate and provides its own MAC address as the reply. Note: Proxy ARP can help devices on a network reach remote subnets without the need to configure routing or a default gateway. Disadvantages of Proxy ARP Proxy ARP can lead to security and performance issues on the network.  It poses a security risk by making the network vulnerable to ARP spoofinf attack. In attacks, malicious devices can impersonate proxies. Intercept or modify traffic between devices. It may introduce inconsistency into the network’s topology. Addressing scheme by concealing device locations and identities. Let see when and how proxy ARP is configured in Juniper by answering below questions which often comes to our mind When do you config

Crypto-policy is a set of access lists that determines the proposals to be used, when configuring VPN phase1 and phase2.
