NCSC Guidance Feed: Preparing for Denial of Service (DoS) Attacks in the Run-up to the 2019 General Election

As the 2019 General Election approaches, the National Cyber Security Centre (NCSC) has issued guidance to help organisations prepare for and respond to Denial of Service (DoS) attacks. In recent weeks, several political party websites have been targeted by DoS attacks, highlighting the need for organisations to be proactive in protecting themselves against these types of threats.

Understanding Denial of Service (DoS) Attacks

A Denial of Service (DoS) attack is a type of cyber attack where an attacker attempts to make a computer or network resource unavailable by overwhelming it with traffic or requests. This can be done through various means, including hacking, malware, or distributed denial-of-service (DDoS) attacks. The goal of a DoS attack is to disrupt or disable the targeted system, making it unavailable to users.

5 Practical Steps to Prepare for and Respond to DoS Attacks

In light of the recent attacks on political party websites, the NCSC has provided a summary of 5 practical steps that organisations can take to help them prepare to respond in the event of a DoS attack.

Step 1: Implement a Web Application Firewall (WAF)

A Web Application Firewall (WAF) is a security system that monitors and filters incoming traffic to a web application. By implementing a WAF, organisations can help protect themselves against DoS attacks by blocking malicious traffic and preventing it from reaching the application. A WAF can also help to identify and mitigate other types of attacks, such as SQL injection and cross-site scripting (XSS).

Benefits of Implementing a WAF:

Improved security: A WAF can help to prevent DoS attacks and other types of malicious traffic from reaching the application.
Reduced risk: By blocking malicious traffic, a WAF can help to reduce the risk of a successful DoS attack.
Increased visibility: A WAF can provide organisations with valuable insights into their web traffic, helping them to identify and address potential security vulnerabilities.

Step 2: Use a Content Delivery Network (CDN)

A Content Delivery Network (CDN) is a system that distributes content across multiple servers, reducing the load on a single server and improving the overall performance of the application. By using a CDN, organisations can help to mitigate the impact of a DoS attack by distributing the traffic across multiple servers.

Benefits of Using a CDN:

Improved performance: A CDN can help to improve the performance of the application by reducing the load on a single server.
Increased availability: By distributing content across multiple servers, a CDN can help to ensure that the application remains available even in the event of a DoS attack.
Reduced risk: A CDN can help to reduce the risk of a successful DoS attack by distributing the traffic across multiple servers.

Step 3: Implement a DDoS Mitigation Service

A DDoS Mitigation Service is a type of service that helps to detect and mitigate DDoS attacks. By implementing a DDoS Mitigation Service, organisations can help to protect themselves against DDoS attacks by identifying and blocking malicious traffic.

Benefits of Implementing a DDoS Mitigation Service:

Improved security: A DDoS Mitigation Service can help to prevent DDoS attacks and other types of malicious traffic from reaching the application.
Reduced risk: By blocking malicious traffic, a DDoS Mitigation Service can help to reduce the risk of a successful DDoS attack.
Increased visibility: A DDoS Mitigation Service can provide organisations with valuable insights into their web traffic, helping them to identify and address potential security vulnerabilities.

Step 4: Conduct Regular Security Testing and Penetration Testing

Regular security testing and penetration testing can help organisations to identify and address potential security vulnerabilities. By conducting regular security testing and penetration testing, organisations can help to ensure that their application is secure and resilient against DoS attacks.

Benefits of Conducting Regular Security Testing and Penetration Testing:

Improved security: Regular security testing and penetration testing can help to identify and address potential security vulnerabilities.
Reduced risk: By identifying and addressing potential security vulnerabilities, organisations can help to reduce the risk of a successful DoS attack.
Increased visibility: Regular security testing and penetration testing can provide organisations with valuable insights into their web traffic, helping them to identify and address potential security vulnerabilities.

Step 5: Develop an Incident Response Plan

An Incident Response Plan is a plan that outlines the steps that an organisation will take in the event of a security incident, such as a DoS attack. By developing an Incident Response Plan, organisations can help to ensure that they are prepared to respond to a DoS attack and minimise the impact of the attack.

Benefits of Developing an Incident Response Plan:

Improved response: An Incident Response Plan can help to ensure that organisations are prepared to respond to a DoS attack and minimise the impact of the attack.
Reduced risk: By having a plan in place, organisations can help to reduce the risk of a successful DoS attack.
Increased visibility: An Incident Response Plan can provide organisations with valuable insights into their web traffic, helping them to identify and address potential security vulnerabilities.

Conclusion

In conclusion, the recent attacks on political party websites highlight the need for organisations to be proactive in protecting themselves against Denial of Service (DoS) attacks. By implementing a Web Application Firewall (WAF), using a Content Delivery Network (CDN), implementing a DDoS Mitigation Service, conducting regular security testing and penetration testing, and developing an Incident Response Plan, organisations can help to prepare to respond to a DoS attack and minimise the impact of the attack.
NCSC Guidance Feed: Preparing for Denial of Service (DoS) Attacks in the Run-up to the 2019 General Election - Q&A

As the 2019 General Election approaches, the National Cyber Security Centre (NCSC) has issued guidance to help organisations prepare for and respond to Denial of Service (DoS) attacks. In this Q&A article, we will answer some of the most frequently asked questions about DoS attacks and how to prepare for them.

Q: What is a Denial of Service (DoS) attack?

A: A Denial of Service (DoS) attack is a type of cyber attack where an attacker attempts to make a computer or network resource unavailable by overwhelming it with traffic or requests. This can be done through various means, including hacking, malware, or distributed denial-of-service (DDoS) attacks.

Q: What are the most common types of DoS attacks?

A: The most common types of DoS attacks include:

TCP SYN flood: This type of attack involves sending a large number of TCP SYN packets to a server, causing it to become overwhelmed and unable to respond to legitimate requests.
UDP flood: This type of attack involves sending a large number of UDP packets to a server, causing it to become overwhelmed and unable to respond to legitimate requests.
ICMP flood: This type of attack involves sending a large number of ICMP packets to a server, causing it to become overwhelmed and unable to respond to legitimate requests.
DDoS attack: This type of attack involves using multiple compromised systems to launch a coordinated attack on a server, causing it to become overwhelmed and unable to respond to legitimate requests.

Q: How can I protect my organisation from DoS attacks?

A: There are several steps you can take to protect your organisation from DoS attacks, including:

Implementing a Web Application Firewall (WAF): A WAF can help to block malicious traffic and prevent it from reaching your application.
