The network security landscape has changed dramatically over the last decade. No longer are threats solely limited to outside actors and hackers with malicious intentions, but they’re increasingly coming from inside your organization as well, making it critical to be aware of the threats and vulnerabilities you face every day as a network administrator.
Here are the top five network security threats and how to defend against them, so you can keep your company’s network running smoothly and efficiently all year long.
Any data sent over the network without encryption is vulnerable to interception. This includes passwords, financial information, and other sensitive data. To protect your data, always encrypt it before sending it over the network. There are two ways to do this: end-to-end or hop-by-hop. End-to-end encryption protects only the sender and receiver of a message, while hop-by-hop protects anyone who happens to be on the same route as message travel across networks.
A vulnerability is a security flaw or weakness in a system. If an attacker finds and exploits a vulnerability, they can gain access to sensitive data or even take control of the device. Poorly configured devices are one of the most common ways that attackers gain access to networks. To defend against this threat, be sure to properly configure all devices on your network, and keep them up-to-date with the latest security patches.
One of the most common network security threats is failing to patch systems in a timely manner. This leaves systems vulnerable to known exploits that can be easily exploited by attackers. To defend against this threat, you should have a patch management process in place that includes testing and deploying patches as soon as they’re available.
One of the most common ways that hackers gain access to a network is by using weak passwords. A weak password is one that is easy to guess or crack, such as a password or 1234. To defend against this type of attack, it is important to use strong passwords that are at least 8 characters long and include a mix of uppercase and lowercase letters, numbers, and symbols.
Cloud misconfiguration is one of the most common network security threats. It can happen when a company doesn’t properly configure its cloud services or when an employee accidentally exposes sensitive data. To defend against this threat, companies should use strong authentication and authorization controls, encrypt data in transit, and monitor their cloud environment for suspicious activity.
A threat is anything that could potentially cause harm to your computer system, data, or network. This includes things like viruses, spyware, hackers, and even power outages. To protect your business, you need to identify potential threats and vulnerabilities so you can take steps to mitigate them.
One way to identify potential threats and vulnerabilities is to look for patterns. This could involve analyzing past security breaches to see if there are any commonalities or trends that you can identify. You can also keep an eye on current events and news stories to see if there are any new patterns emerging. Additionally, you can monitor social media platforms for signs of unusual activity or behaviors that could indicate a threat.
One way to identify potential threats and vulnerabilities is to ask yourself what could happen. What are the risks? What could go wrong? By thinking through different scenarios, you can start to get a sense of where your weaknesses lie.
For example, one scenario might be that an employee has access to both the finance department and human resources files. The risk in this situation is that an employee could steal sensitive information from either department.
A second scenario might be that an employee needs access to servers for two days each week but does not need access on Fridays when there are no updates being made. In this case, Friday would represent a vulnerability because there would be no oversight of their work during those two days of the week when they should not have access to servers. There are many possible vulnerabilities, which is why it is important to identify them before they become real problems.
When you’re trying to identify potential threats and vulnerabilities, it’s always a good idea to ask other people for their opinions. Talk to your friends, family, and co-workers – anyone who you trust and who might have helpful insights.
SSL Certificate is the best way to keep your networking websites safe from vulnerabilities. It encrypts all the information that is sent between the user and the server. This means that no one can eavesdrop on the communication or steal any data. SSL Certificate also authenticates the identity of the website, so users can be sure they are sending their information to the right place.
Website owners can buy SSL certificates from many SSL providers like reputable Certificate Authority (CA) like Symantec, GlobalSign, or Comodo. If your website is having multiple subdomains then you can purchase a wildcard SSL Certificate like Thawte wildcard SSL, Comodo PositiveSSL Wildcard, RapidSSL Wildcard, etc. These Wildcard SSL Certificates are available from many different providers, so be sure to shop around for the best deal.
If you’re looking to create more secure systems, you’ll first need to know where your biggest vulnerabilities are. To better understand the security of your network, it’s important to recognize different types of threats and vulnerabilities that may exist. By knowing the specific kinds of attacks, you should watch out for, you can take proactive steps toward creating more secure systems now and in the future.
