Migration and changing of packet filter has always been a hectic, tedious and time taking process. A successful migrating of packet filter has to have full visibility of network on the whole surface of attack. A constant monitoring is also required so that the vulnerabilities and policy violations which are introduced through configuration of settings and risky changes can also be checked.
There are 6 key strategies that can be implemented to reduce any risks involved and also make things easier for migrating to next generation of packet filters. These are as follows
- Normalization of all the data across packet filter types, providers and network devices
- Examination of packet filter for full visibility of network
- To optimize performance and security always cleanup the sets of rules
- For any kind of risk analysis conduct “what if” analysis
- Always go for more advanced features for the prevention of attacks
- Automation of packet filter management
For a successful firewall migration these six steps need to be learnt and implemented to make sure no risky changes need to be made or network configurations.
Features to look for when considering packet filter for enterprise:-
Here are few things that need to be looked upon when going for the next packet filter for the enterprise.
Keeping in mind continuous evolving of threat scenarios there is an essential need to move beyond the conventional model for packet filters and revisiting of security parameters is also necessary.
Keeping in mind all the threats:-
A large number of threats arise from the application based on web and services that penetrate the corporate networks. This clearly enforces the enterprises to consider all kinds of threats whether known or unknown in the selection of security platform for the enterprises network.
Blockage of emerging threats:-
The pace of deploying packet filters by service providers and enterprises is increasing to take the applications in control and also block all kind of emerging threats. Next generation packet filters are designed to by focusing on the needs of the enterprises, which include some advanced features like
- Application level inspection
- Intrusion prevention
- Granular policy control
When the stage of selecting a packet filter comes for the security of the enterprise’s system lot of times IT professionals struggle in right integration of granular security functions. This compromises the efficient working and effectiveness of the firewall migration. The continuity should be kept in learning key features which can be effective in choosing a packet filter for an enterprise in the modern times.
