Final answer:
Prevalent security issues faced by Information Technology (IT) today include data breaches, denial of service attacks, phishing, and viruses. Strategies to address these issues include encryption, firewalls, software updates, and user education.
Step-by-step explanation:
Prevalent security issues faced by Information Technology (IT) today include:
- Data breaches
- Denial of service attacks
- Phishing
- Viruses and malicious programs
A data breach is a security incident where unauthorized individuals gain access to sensitive, protected, or confidential data. Denial of service attacks involve overwhelming a target system with excessive traffic or requests, causing it to crash or become unresponsive. Phishing refers to fraudulent attempts to obtain sensitive information, such as passwords, usernames, or credit card details, by disguising as a trustworthy entity. Viruses and malicious programs are software designed to cause harm to computer systems.
To address these security issues, organizations and individuals can employ strategies such as implementing strong encryption methods, using firewalls to protect networks, updating software regularly, and educating users about safe online practices.
