DNS and DoS attacks 'the most difficult to protect against'

Share this article:

More than half of businesses rate denial of service (DoS) attacks as highly effective, yet more than three-quarters rely on firewalls for protection.

According to research by F5, which polled senior IT managers at 1,000 large organisations, 53 per cent of respondents rated DoS attacks as highly effective and 79 per cent relied on firewalls to protect against them – yet 42 per cent said they have had a firewall fail against a network-layer DoS attack.

Also, the survey found that between 40 and 45 per cent of respondents frequently see DNS attacks, application-layer DoS attacks, injection attacks, cross-site scripting and network-layer DoS attacks, the latter being reported as the most frequent. DNS attacks were rated as the most difficult to protect against.

Gary Newe, technical director at F5, said: “With cyber attacks becoming more persistent and frequent and infrastructures more complex, enterprises find it increasingly challenging to defend their applications and data.

“While many organisations can view insider threats as the most difficult to defend against, the research clearly demonstrates that external threats remain a potent force and companies need to be aware of the most effective ways to safeguard themselves.”
