Cyber security is a vital area of IT that focuses on the protection of an organization’s sensitive data from attack by hackers and other malicious actors. It is a field that is becoming increasingly professionalized, with colleges offering majors in cybersecurity and bootcamps providing specialized training to prepare people for careers in the field.
A cyberattack can have disastrous consequences for an organization, with a hit to its reputation and a drop in stock value often the result. In addition, a loss of confidential customer information can result in lost business and lawsuits, while an infection from malware can disrupt workflow and lead to a loss of productivity. A well-established cybersecurity system can help an organization avoid such issues, which is why businesses are constantly working to improve their cyber security systems.
The key principles of cyber security are Confidentiality, Integrity, and Availability. Confidentiality is about protecting the privacy of data and ensuring that only authorized parties can access critical information or functions. Integrity is about ensuring that the functions and data in a system are accurate and complete, while Availability is about making sure that systems and information are available when needed. Common technology used to protect these entities include next-generation firewalls, DNS filtering, anti-malware software, and antivirus solutions.
Moreover, advanced cryptography and encryption can be employed to keep information private from prying eyes. In addition, tools such as microkernels and automated theorem proving can be used to verify that critical algorithms and code meet their specifications. Backups are also crucial for maintaining integrity and preventing data loss, as they are stored in multiple locations to prevent one copy of an important file from being stolen or damaged. MDR
