With the development of network technology, new types of attacks are also emerging, posing a serious threat to enterprise network security. For enterprise security teams who are trying to deploy and manage security controls to prevent advanced attacks, threat intelligence is very important. A good way to enhance threat assessment is to add threat intelligence into existing information security plan. In this way, more critical data will be provided to show what kinds of security controls can be deployed in an enterprise environment to prevent the latest attacks. In general, the threat intelligence refers to the information which is collected by enterprises from a variety of sources and used to analyze the latest threat media. Therefore, it is necessary to add threat intelligence into information security plan in order to protect against attacks.
How to add threat intelligence into information security plan
Recently, many enterprises try to optimize security controls as well as adjust information security plan by taking advantage of IT security risk management technology. However, these methods are not enough to manage risks effectively. Therefore, enterprise administrators are advised to add threat intelligence into information security plan so as to protect against the latest attacks and improve incident response speed. There are three ways for enterprises to get threat intelligence: build their own team of researchers and analysts and start from scratch to create a threat intelligence program; subscribe threat intelligence service from secure suppliers; join Information Sharing and Analysis Center.
After selecting threat intelligence sources, enterprises must find suitable ways to add threat intelligence into their information security plan. Standardized (usually XML) threat intelligence resource and information flow can be integrated into a variety of safety devices. For instance, known malicious IP addresses can be entered into firewall and prevented. Meanwhile, known malicious domain names can be prevented by DNS and malicious downloaded files can be identified by network monitoring tools. Enterprises can also configure SIEM system to integrate threat intelligence resources in order to identify the infected host. Additional threat data of follow-up surveys are able to be used for further analysis of different systems.
One big selling point of threat intelligence is that it can provide useful information to enterprises, so attacks can be prevented before starting. By monitoring attacks designed for specific software, system or industrial in intelligence threat, enterprises are able to confirm whether the software or system they use is vulnerable or not. Therefore, they can deploy mitigation measures before the emergence of attack. It seems reasonable to collect and manage internal threat intelligence. However, in order to perform such work more effectively by using other companies’ data, enterprises may as well turn to the third-party service providers. Service providers are responsible for validating and processing inbound intelligent information and data, so the only thing enterprises need to do is to import related data into internal tool.
Enterprise information security plan requires sufficient flexibility and more other methods should be added into it to improve the decision-making process. As the threat is becoming more and more sophisticated and targeted, enterprises need to take advantage of all scientific means to realize safe management.
