Web Application Hacking
If you’re running a business website, then you need to be able to answer the question “What is web hacking?”. This may seem a really easy question to answer, but it’s important to understand that web hacking has had different meanings at different times and will probably continue to do so as the internet develops.
What is web hacking now?
The answer to the question “What is web hacking now?” is that it is a wide range of potential activities, from old-school mischief-making to highly-sophisticated digital heists via 21st-century "hacktivism".
This means not only that companies, even SMBs, have to keep on top of their security game to try to stop hackers infiltrating their systems, but they also have to work on the assumption that, despite their best efforts, those defenses are going to be breached from time to time. This means that they also need to think about safeguarding their data when this happens.
The good news is that it is more than possible for SMBs to keep themselves and their data safe without breaking the bank. Here are some tips.
Take the security of your servers very seriously
Over recent years, there has been continuous growth in the number of cyberattacks undertaken for financial gain. In general, the target of these attacks is a company’s data and the place to find most of that data is on their servers, particularly their database server, and any places its data is backed up or archived.
It’s important to understand that the value of a company’s data is partly based on quantity and partly based on quality. This means that even an SMB can be of huge interest to hackers if its customers (or employees) are in a high-value demographic.
There are two key points to take away from this. The first is that you absolutely must have robust server-side security. Given that most SMBs will probably use a third-party web-hosting service this means that you must prioritize security when choosing a vendor. Other high priorities should be uptime, page-load time, customer service, and technical support. Only if you are happy with all of the above should the price be considered.
The second is that you must store all sensitive data encrypted regardless of where it is in your systems. This is the only way to ensure that it is useless to any hackers who break into your server. You also need to have a hacker-proof backup process so that you are protected from threats such as slow-acting ransomware. These try to infiltrate your systems by stealth and stay hidden until your backup is compromised, leaving you more vulnerable to data loss (although not data theft if you have encrypted your data).
Remember to protect all local devices, including mobile ones
Your computers and mobile devices are probably what you use to connect to your website (and other systems). This means that if they are compromised, a hacker could potentially steal valuable account details and use them to access your website (and indeed other systems). Even if you don’t store account details in your computers and mobile devices, they could still be compromised through spyware such as keyloggers.
This means that your computers and mobile devices must all be protected by a robust anti-malware solution with an integrated firewall. If you have people working from outside your business premises, then it’s strongly recommended to invest in a virtual private network solution to ensure that they (and your systems) are kept safe even when they are using a questionable connection.
Choose your website’s software with great care
The main content management systems can all offer a high level of security, but they don’t offer it “out of the box”, quite the opposite in fact. Hackers can easily inform themselves of the capabilities of open-source software and they do. This means that you need to do likewise and make sure to customize your default settings and assign permissions appropriately to provide maximum protection from hackers.
Third-party add-ons, by contrast, can be security nightmares. Some of them are outright, intentional malware. Others aren’t intended to cause harm but are so badly written that they create all kinds of problems. The safest option by far is to stick to mainstream options with strong community support. Even then, do your research and try to test them out thoroughly before you deploy them in production.
Whatever software you choose, commit to keeping it updated. Out-of-date software of any sort is an invitation to hackers and out-of-date open-source software is beyond tempting for them.
