In information warfare, the need to develop SIEM architecture has become a crucial factor due to the existence of ever-growing cyber threats and their creators – cyber pests.
Threat Intelligence Feeds, in fact, are an actionable threat data related to artifacts or indicators collected from any third-party vendors in order to learn from other company’s visibility and access to enhance your own cyber threat response and awareness. The example of these third-party vendors includes Kaspersky Threat Intelligence and Alient Vault OTX. Threat Intelligence Feeds concentrate on a single area of interest and they are delivered online. For instance, these data feeds can be about IP addresses, hashes, or domains.
In case of a cyber security incident, logs play a vital role in various activities such as establishing the point of compromise, tracing the actions of an attacker, further investigation, and regulatory proceedings before an authority, etc. Logs are generated by every application, let it be a general application like performance monitoring or security specific application like a firewall.
With a colossal surge in cyber-attacks and high reliance on technology in this digital age, ensuring the security of data and information have become a daunting task. Cyber threats are accelerating significantly even faster than the enhancements businesses are making. Computer networks have become bigger and their interconnectivity using a Wide Area Network (WAN) is worldwide due to globalization. It is hard for current IT security solutions to prevent cyber-attacks. According to Symantec’s 2019 Internet Security Threat Report (Volume 24), Formjacking attacks compromised 4800+ websites almost every month. Supply chain attacks also increased by 78% in 2018. Furthermore, more than 70 million records were also leaked or stolen due to poor configuration of S3 buckets.
If an organization properly implements a SIEM solution, it efficiently draws attention towards warning signs as well as suspicious activity within the network. With the ever-evolving cyber space, continuous security monitoring has become exceedingly important. The benefits of SIEM also extend to understanding business and technology environments, monitoring availability and performance, issue diagnosis, and creation of a report on network activities.
