5 network attacks that your business should worry about
If you have been following the news recently on network attacks, you will have heard of the WannaCry Ransomware, which recently wreaked havoc across the globe. Large entities, including the National Health Services in the United Kingdom, were affected.
Ransomware is but one of the types of Network Attacks that have been getting common over the past few years. The following are some of the most common Network Attacks that businesses should be on the lookout for;
- Browser Attacks
- Denial of Services Attacks
- Ransomware Attacks
- Brute force attacks
- Phishing Attacks
- Browser Attacks
Browsers, such as Chrome, Mozilla and Internet Explorer, have the important task of acting as an interface between individual computers and the World Wide Web. It is hardly surprising, therefore, that browsers form one of the largest frontiers on which attacks are launched on networks across the globe.
Browser attacks are usually launched using Trojan horse types of malware. They are also referred to as man-in-the-browser attacks. This has similarities to Man-in-the-Middle (MITM) attacks and act by interposing themselves between the network and the browser.
The infection exploits security vulnerabilities in any of the browsers that can be found out there. They then covertly make modifications to web pages. The majority of network attacks that occur out there are Browsers attacks. They can be particularly devastating, which is why we encourage organizations to enrol for any one of our free webinar for managed IT solutions and security.
- Ransomware Attacks
We have already mentioned the WannaCry Ransomware attack, which got global attention after infecting and holding at ransom data on hundreds of thousands of computers across the globe. The term Ransomware refers to a type of malware that does the following;
- Infects computers and blocks access to important files
- The infection may also block access to the entire computer
- Demands that a ransom be paid before access can be granted
How Does Ransomware Spread
Malware infections have various ways of spreading from one computer to the other. Ransomware usually takes the form of a Trojan, which tricks people into opening infected email attachments. However, the recent WannaCry Ransomware came with the ability to automatically infect computers.
Ransomware should be of particular worry to businesses because, as was the case in the recent situation, they can be very costly. The problem with most organization is that they are not really proactive when it comes to keeping their systems safe. Most of the entities that were affected were still running Windows XP based systems.
- Denial of Service Attacks
Denial of Service, (DNS) attacks are another of the most common types of network attacks that businesses should be worried about. The entire aim of a DNS attack is to overwhelm a network and make it unavailable to its intended users. One of the reasons why this type of attack is so widespread is the fact that it is so simple to accomplish.
All that an attacker needs to do in order to overwhelm your business is institute a high number of requests. This prevents legitimate users from getting through and can really be devastating, particularly for online businesses. Any period that your website spends offline translates into lost revenue.
- Brute Force Attacks
This is another type of attack that you should be worried about as a business. Brute force attacks rely on relentless trial and error to gain access to people’s data. The attacker simply makes a countless number of guesses at a computer user’s password. Eventually, the attack is bound to yield results, after which your business will be at the mercy of the attackers.
It is for this reason that most systems that require passwords will only allow three attempts at gaining access. Afterwards, the individual is locked out of the system until the password has been reset.
Unlike brute force attacks, phishing uses guile to gain access to the victim’s computer. It is therefore one of the least technically sophisticated, yet more devastating attacks that businesses around the world should be on the lookout for.
Phishing attacks usually come disguised as legitimate causes, and attempt to get people to hand over their passwords or banking details. Some of these attacks can be elaborate, although, with a lot of the Phishing attempts that are floating around out there, it can be very easy to see through the attempt.
