Question 8
A company stores data about employees on networked computers. Discuss the methods available to maintain network security and protect the data from cyberattacks.
Worked Solution & Example Answer:A company stores data about employees on networked computers - Edexcel - GCSE Computer Science - Question 8 - 2021 - Paper 1
Step 1
Validation and authentication techniques
Answer
To maintain network security, companies can implement robust validation and authentication techniques. This includes utilizing access control systems, physical security measures, and firewalls to ensure that only authorized personnel have access to sensitive data. Multi-factor authentication (MFA) can also significantly enhance security by requiring users to provide multiple forms of verification.
Step 2
Security issues associated with cloud storage
Answer
Using cloud services introduces specific security considerations. It is essential to routinely assess the security measures employed by the cloud service provider and to ensure that data is encrypted both in transit and at rest. Regular backups should also be conducted to secure data against loss or breaches.
Step 3
Different forms of cyberattacks
Answer
Understanding various forms of cyberattacks is vital in protecting networked data. This includes recognizing techniques such as phishing, shoulder surfing, and unpatched software vulnerabilities. Comprehensive user training on recognizing and avoiding such threats can further mitigate the risk of successful attacks.
Step 4
Vulnerability identification methods
Answer
Implementing methods to identify vulnerabilities is crucial. This can involve penetration testing to simulate attacks and uncover weaknesses, as well as using commercial analysis tools to assess the network's security posture effectively. Regular audits of network and user policies can also help in understanding potential exploitation risks.
Step 5
Software security practices
Answer
Adopting best practices in software development is essential to prevent vulnerabilities. Conducting code reviews during the design phase and enforcing secure programming languages standards can minimize the introduction of security flaws. Developers should also be trained in secure coding practices to recognize potential issues.
