What Is Cyber-Security?
Cyber-security is the field of computer security that protects computers, networks and software systems from malware, viruses, spyware, worms, hackers, extortion attacks and more. More than ever before, we are entrusting our personal and professional data as well as critical infrastructure services like energy grids, financial services, hospitals and transportation networks to digital technologies. Cybersecurity solutions must be able to keep up with this pace of growth and change while also being flexible enough to adapt to new threats as they emerge.
A cyberattack can be as simple as a phishing email or as sophisticated as a targeted attack against a specific employee or group of employees for reasons ranging from monetary gain, revenge to corporate espionage. To combat these attacks, a cybersecurity solution should be able to offer a comprehensive set of tools that include next-generation firewalls, Domain Name System (DNS) filtering, anti-virus protection, encryption technology, and advanced malware prevention.
An effective extended detection and response (XDR) system can provide the visibility and context needed to identify and prioritize threats. This allows analysts to focus on the most pressing vulnerabilities and improve productivity. Other security controls should include backups to increase redundancy and the use of encryption to ensure confidentiality. An information security management system based on ISO/IEC 27001 can help ensure compliance and an overarching management process to support continuous improvement. This standard offers guidance to organizations of all sizes and industries. It also supports best practices for assessing risk, protecting sensitive information and providing an incident response framework.
