Understand the Key Web App Attack Vectors
Start by familiarizing yourself with hackers’ favorite ways into apps, such as:
- SQL injections
- Cross-site scripting (XSS)
- Denial of service (DoS) attacks
There are many more, of course, and new ones are being dreamed up every day. Make sure your security team stays abreast of all of these and understands exactly how they are used.
Bake Security Into Your Web App Development
With developers focused intently on the functionality of an app, security is often an afterthought in the development process. A web app can have a security hole as basic as leaving login credentials in default mode during development, so developers aren’t stuck logging in all the time to make minor code tweaks. If the app goes public that way and hackers find out about it, it’s like turning the Pirates of the Caribbean loose in your network.
Before an app goes live, blast it eight ways to Sunday with common intrusion techniques, and then test it some more when it goes live. Never underestimate hackers’ ability to find gaps in your web apps. They know the gaps are there if they keep looking long and hard enough.
The longer you delay them, the more likely they’ll give up and start prowling someone else’s network.
Invest in Intrusion Detection and Logging Technology
Modern intrusion detection software tracks network device logs in real time and flags any anomalies. Most web users do the same things the same way every day, and any unusual traffic usually means somebody is up to no good.
You might notice, for example, a rapid decline in performance on a section of your network. With the right software, you can scan the logs in real time and discover that an intruder is flooding one node on your network with requests: a standard DoS attack profile.
Install a Web Application Firewall
Layer 7, the application layer, really needs its own firewall — separate from the one you install at the network level. Why? Because there are so many attack vectors between the network and app layers that you really need to move your attention further up the infrastructure stack to secure everything.
A web application firewall (WAF), working in tandem with intrusion detection and log management, can block certain kinds of traffic based on specific traffic patterns that crop up only with layer 7 attacks.
Outsource to Security Experts
The above barely scratches the surface of web application vulnerabilities. You can have a WAF optimized to perfection, deploy state-of-the intrusion detection and real-time logging, and still get hacked.
If web apps go live with an easy-to-exploit security hole, hackers can stroll right past your intrusion detection and WAF because their traffic will look like everybody else’s and won’t send up any red flags to block it.
With security, the key is to have people who devote their lives to doing nothing but foiling hackers and securing systems. Because attack vectors change daily, it’s important to watch zealously for the latest attacks and get systems patched. And it’s about creating so many hurdles for hackers that they get fed up and look elsewhere.
