What Is Digital Security?
Digital security is a set of best practices and tools used to safeguard your data and online identity. It includes password managers, antivirus software, and even parental controls. Using these techniques will prevent a hacker from breaching your computer system and accessing personal information. It will also keep your network secure from attacks by intruders that can cause a denial of service, or expose your sensitive information to unauthorized users.
A computer virus or worm is one example of malicious code that could cause a breach of security. Other threats include privilege escalation, where attackers with limited or restricted access are able to gain more privileged access to the system, such as becoming root and having unrestricted control. Cryptographic techniques can be used to protect communications between systems, reducing the likelihood that sensitive information can be intercepted and modified. The ability to verify the correctness of algorithms and code is also a key component of digital security, with formal verification methodologies like automate theorem proving helping to ensure that critical software is correctly written.
Regulatory compliance is another aspect of digital security, as many laws require companies to protect sensitive customer information. Businesses should consider the risks associated with these regulations, as failure to comply can lead to fines or loss of business.
