Dealing with network attacks today can be a bit like finding a needle in a haystack. We need to be able to quickly determine what is malicious from what is safe, then automatically take action to deal with what we just discovered. This approach to securing networks is critical today as attackers continue to evolve their techniques. Once we can deal with these new attacks, the next challenge is to understand the nature of the attack. Prevention is key, but understanding the nature of the attack helps to determine if the attack is part of a larger campaign, a targeted attack on your company, or just broad spectrum malware noise. Today, not only do we need a real-time approach to preventing known and unknown attacks, but we also need the details about these attacks so we can determine the full scope of the threat. This contextual threat intelligence can help us determine what we need to focus on. Attacks continue to evolve. How we prevent them and learn about them needs to evolve as well.
