and generating awareness formed part of activities of SASE. A vast network of high altitude observatories was also established. Planned reconnaissance of avalanche prone axes in J&K‚ HP was conducted and Avalanche Atlases were prepared. Cold Laboratory was established in 1990 and research on snow physics and mechanics was initiated. In nineties‚ the installation of Automatic Weather Stations (AWS) was initiated to densify the network of weather observation station in Himalaya. SASE steadily stood

Network Security Some DoS attacks can be avoided by applying vendor patches to the software that has been compromised. Another way to deal with DoS attacks in the case of an attack coming from a number of known IP addresses is to put up a rule to drop all incoming traffic from those known attackers. Yet another way to deal with these types of attacks is to set up packet filters. This will act as a proxy for connections. Once the handshake is validated it will be forwarded to the correct destination
