In the world of cyber warfare, the internet has become a vital part of every walk of life. When it comes to downloading a file from the internet to your laptop or PC, you cannot be guaranteed a 100% safety due to the existence of fast and sophisticated cyber threats. Security vulnerabilities, data breaches, viruses, and malware have become very common and result in exploitation of the originality, integrity, and authenticity of any file you download from the internet.
If you are familiar with IT security, you must have heard CIA triad: a security model that covers different parts of IT security.
Being one member of CIA triad, file integrity refers to the processes and implementations aiming to protect data from unauthorized changes such as cyber attacks. A file’s integrity tells if the file has been altered by unauthorized users after being created, while being stored or retrieved.
Data is a raw material, which is often unstructured, extracted in massive quantity, and requires processing before calling it an information and actionable intelligence. A good example is the Indicators of Compromise (IoCs). A big list of domain names or IP addresses can be ingested into the SIEM system to identify whether this list contains any malicious IP or not. If any suspicious IP is detected, then we can term this data as an actionable intelligence which has been evaluated from reliable sources, processed and enriched. Now, it can be used to identify trends, attack profile, and possible threats. In this article, we will see how data is gathered, processed, and act as an actionable delivery.
With the rise of technologies such as Internet of Things and cloud storage solutions, data concerning almost every aspect of our lives are highly connected, making us and our businesses vulnerable to cyber-attacks. Since we are way past the point of turning our back to new technologies, we need to learn how to protect our data while keeping up with the recent developments.
Every business has its assets: things that are of value. They can be land, cash, equipment, vehicles, buildings; but also they can be digital, such as applications, business processes, software, trademarks, up-to-date customer or client list on CRM software, copyrighted material, business websites, business blogs and so on.
