Cybersecurity threats in 2022
Cybersecurity threats are threats that focus on gaining access to an organization’s sensitive data. Unfortunately, it is called a threat for a reason. Attackers generally want to gain access in order to steal data. There are many different ways and reasons that attackers want to get into an IT environment, so let’s take a closer look.
Sources of cybersecurity threats
The sources of emerging cyber threats and attacks are seemingly endless. There are all types of reasons and motivations why someone wants to break in. Let’s look at some of the more common sources of cyber attacks and see if we can dig a little deeper.
One source of cyber threats is corporate spies. The larger your company gets, the more likely it is that competitors or researchers will want to steal sensitive data. Cybercriminals may attempt a data breach for financial or personal gain. When it comes to safeguarding trade secrets, make sure to take extra precautions.
If you are engaged in activism for some cause, DDoS and hacktivists may attack your website to prove a point. These cybercriminals may want to do something as simple as defacing your website or they may want to put you out of business.
Another source of cybersecurity threats are disgruntled employees. A disgruntled employee may want to steal data or information to get back at the organization. Ex-employee cybercriminals may steal sensitive corporate data for financial gain.
Hackers or cyber criminals are people who seek to exploit vulnerabilities and breach critical infrastructure. In today’s media, the term hacker has a generally negative connotation, and the truth of the matter is we may not know their motivation.
These are just a few items in the cybersecurity threat landscape. The fact of the matter is that a solid information security strategy and policy are paramount to keeping hackers out, no matter the motivation.
Now that we’ve reviewed the profiles of threat actors, let’s look at some types of cyber threats and protect yourself from them.
Here are some of the most common cyber threats you will encounter in your environment and some things to think about when trying to protect your corporate data.
The first type of cyber attack, in this category, is malware/spyware. In this scenario, cybercriminals will attempt to install malware to gain access to a system or network. Let’s take a look at some more specific types of malware.
A trojan is one of the most classic malware pieces out there and one of the easiest to use to access an environment. A trojan looks like a standard piece of software to the end-user, so when they think they are installing a new app, your network gets a special surprise.
Ransomware is currently one of the most active pieces of malware around. You are constantly seeing stories about ransomware in the news. A sophisticated form of ransomware will get into your computer networks and may do nothing for some time, making it difficult to detect.
When the ransomware activates, it begins to block access to your systems. At this point, your only hope is to recover your systems or pay the ransom.
A wiper attack is what it sounds like; a malicious attack that will delete data stored on your computer systems. These cyber-attacks cause havoc.
A drive-by download is an unwanted download of malware that happens while your users are unaware. This cyber threat comes in a couple of different flavors. First of all, a user may end up downloading a piece of software by clicking a link or opening an email. Secondly, it can tie back in with a trojan when a user thinks they are downloading something legitimate, and it turns out to be malware.
Rogue security software
There’s nothing worse than a user that thinks they did something wrong. They may realize that something is wrong with their computer and try to fix it on their own. There are many imposter security software packages out there that seem like they will help out an end user but end up doing more harm than good.
Social engineering attacks
We’ve spent a lot of time talking about hackers getting into your network. Now, let’s talk about hackers getting into your user’s heads. These attacks are called social engineering. It can be as simple as someone posing that they work at your helpdesk and asking a user for a password, or it could be more sophisticated.
A phishing attack tricks an end user by stealing credentials via email, text messages, etc. Phishing happens when an email link looks like it’s coming from a legitimate site and asks you to enter your login information.
Homograph attacks are interesting because they make users think they connect to more innocent systems, like a phishing attack. Homograph attacks use identical letters and numbers to make things look and feel legitimate — think of things like swapping a capital letter I for a lowercase letter l in many fonts.
Distributed denial of service (DDoS) attacks
A distributed denial of service attack, also known as a DDoS, denies service. The theory behind these attacks is they overwhelm the target system entirely, making it unusable and denying service.
Botnets are devices used in DDoS attacks. These bot devices are connected to the internet and controlled by the attackers. In some cases, botnets have been created by exploiting devices on the internet.
TCP SYN flood attack
An SYN flood attack takes advantage of part of the TCP handshake protocol. When creating a TCP connection, the client first sends a synchronize or SYN message to the server, acknowledging the connection, aka ACKs. The client is then supposed to respond with an ACK of its own to complete the connection. In this case, the client never responds with its ACK but continues to send SYN messages instead, ultimately flooding the connection and rendering it useless.
A teardrop attack focuses on sending incomplete packets to a destination machine. The target can’t assemble the packets and is overwhelmed by the requests it can never complete.
Another attack vector is targeting passwords to a system. There are several different ways to accomplish this.
Brute-force password guessing
A brute force attack keeps generating passwords and attempting to access a system. It systematically keeps changing the password until the correct combination is found.
A dictionary attack is a little bit different. Instead of randomly trying to figure out the password, a dictionary attack uses a dictionary of commonly used passwords. Passwords are meant to be protected and kept private. If your password has been made public in a data breach, change it.
A zero-day exploit is an exploit that becomes available before a vendor has a software patch ready to mitigate it. In most cases, attackers keep their exploits secret, and they are made available on “day zero” when they cannot be immediately fixed. In some cases, hackers or researchers may let a software vendor know that they have found a vulnerability before releasing it.
Man in the middle attack (MITM attack)
A man-in-the-middle attack is when a malicious actor intercepts the communication between two entities.
This method focuses on hijacking a communications session. They act as the sender or receiver and begin collecting and transmitting data as their presumed persona. If they seize a session after system access has been granted, they can gain access quickly.
A replay attack is when data is saved during a communication session and then replayed later. If authentication happened during a dedicated session, this is another “easy” way into a system.
Why is it necessary to protect against cyberthreats?
As you can see from this list, there are many cyberthreats in today’s landscape. It is vital to protect against them, so data is not stolen or compromised, and systems remain accessible to users.
Any security incident has a cost associated with it. Some are larger, and some are smaller. One way to help determine the potential impact of data loss or a data breach is to classify your systems and data.
Top cybersecurity challenges
There are many cybersecurity challenges when it comes to protecting an organization’s data and systems. In today’s world, there are a couple that stands out.
Mobile devices are difficult to secure
First and foremost are mobile devices. These bring all sorts of threats to the environment, especially with the rise of BYOD. Besides, mobile devices may be connected to a corporate network but managed by an individual. Mobile devices are still vulnerable to common attacks like malware and phishing attacks.
Complexity of cloud environment
There has also been a rise in cloud adoption in the last several years, but cloud environments can be complex. Everyone loves the adage of how easy it is to get started with the cloud. Just grab a credit card, and you’re up and running in no time. If organizations don’t have cloud policies and procedures in place, this can quickly become a huge security risk. Additionally, organizations may not fully understand their new cloud platform and may not secure it properly. Worse, they may assume they don’t even have to worry about security anymore since they are using the cloud.
How to protect against and identify cyberthreats
There isn’t an easy answer when it comes to protecting against and identifying cyberthreats. The first step is to make sure you understand the basic types of cyberthreats out there and start thinking about them regarding how they can impact your organization.
There are a few places to get started when it comes to protecting against cyberthreats. First and foremost, is to make sure you understand the applications and data in your environment and the cost associated with downtime, data loss, and data leaks.
If you have a disaster recovery plan in place, this is an excellent place to get started. After all, a cyberthreat is a type of disaster. Be sure you have a good understanding of the Business Impact Analysis (BIA) that has been done in your organization. If no BIA has been done, this is an excellent place to get started.
After you understand how much these events cost, you can begin to put together solutions to protect against them. How much an incident will cost you will significantly impact your ability to mitigate security risks in your environment.
If an incident is a low impact in terms of cost, you will probably not be making a significant investment to protect that system. Likewise, if a system is deemed mission-critical and has a high price with an incident, you will preserve that system differently.
How can you detect cybersecurity threats before they occur?
Threat detection is no easy feat, but protecting your assets before they are exploited is a great first defense line. This, of course, is not a substitute for an incident response plan, but some work upfront may be able to lessen the severity and number of actual security incidents.
Monitoring systems in your environment are crucial to detect threats before they occur or as they are occurring. It is essential to have a monitoring system that can understand your environment’s baseline and alert you appropriately to things that are out of the bounds of normal. Alert fatigue is accurate, and if the monitoring system is ignored, it won’t help you detect threats.
OWASP threat model
OWASP is the Open Web Application Security Project and a nonprofit foundation focused on software security. Getting involved with OWASP is a great way to get started on your journey to protecting your applications. OWASP also has local chapters throughout the world, making it easy to connect with like-minded individuals to solve everyday problems.
One area that OWASP can aid practitioners in is threat modeling. Threat modeling is a method of examining an application to identify potential vulnerabilities and threats that it may be susceptible to.
Best practices for cyber defense for businesses
If you’re looking to build your cyber defenses, here are some areas that you should consider taking a look at when you are coming up with your strategy for mitigating cyberthreats in your environment. Now that you know more about the cyberthreat arena, you may have a better idea of prioritizing the following cyber defense mechanisms in your environment.
User education and awareness
Users are one of the most significant weaknesses in coming up with a cyber defense strategy, as we can see by the threat landscape. Investing in programs to aid user education and awareness will never be wasted funds. Many organizations often overlook this area since it can be harder to measure and is less tangible than other defense mechanisms.
The network is, of course, another central focal point for hackers, as you can see by many types of threats. Investing in network security is a great way to get started in ensuring you can mitigate these threats. A strong network is an excellent defense against hackers. Penetration testing is a must when it comes to figuring out the weaknesses in your network, and it is often best done by a neutral third party. Sometimes we can be blinded to faults when we’re used to seeing the same networks and systems.
Preventing malware is a great way to protect your assets. This, of course, ties back to user awareness and training, but software tools can help you prevent malware from getting into your network. Think basics like ensuring all endpoints have antivirus and antimalware software installed on them and more advanced systems to help stop malware in its tracks.
Removable media controls (3-2-1 Rule)
In the backup world, we like to talk about the 3-2-1 Rule to help protect data. As stated, the 3-2-1 Rule means you should have 3 copies of your data on 2 different media types, with 1 being off-site. This helps protect you if your primary data (or even your primary site) is compromised.
There are so many different software pieces that make a business run, not to mention software that controls hardware! In all cases, your software or hardware vendor likely has something they call a hardening guide or a list of secure configuration best practices. It is always a good idea to make sure your components are configured with security in mind.
Managing user privileges
Since we know our users are often the target of so many cyberthreats, it is essential to manage user privileges. You may have also heard of the principle of least privilege. This means that we need to ensure that our users ONLY have the permissions they need to perform their essential job functions, nothing more, and no privileges that are just nice to have. There should always be a business driver for granting users additional rights.
Unfortunately, it isn’t if you have a cyber incident in your environment, but when you have a cyber incident. That is why it is so important to have cyber incident management processes in place so that crucial personnel knows precisely what to do in the case of an incident. At the core of incident management are quick responses designed to mitigate risk and damage.
Be sure you’re monitoring your environment, from your network to your servers to even your backup environment. A sound monitoring system can help you determine if a cyber incident has already started or will occur. For example, suppose you’re monitoring backups and see they are suddenly larger and taking longer than expected. In that case, that could be a sign that ransomware is beginning to encrypt your data.
Home and mobile working
It is imperative to have policies on home and mobile working since so many are taking advantage of technological advances. Be sure to have a clear policy on what activities are allowed on corporate devices, even at home. Furthermore, if you have a BYOD policy, make sure there are controls to protect their systems from malware.
Review your processes
Last but not least is to periodically review the processes and policies you have in place regarding cyberthreats. The threat
landscape is rapidly changing, and it is essential to make sure you can switch to protect against these threats quickly.
What are the different types of security threats?
There are different types of security threats like malware, insider threats, or unauthorized access to data. To protect against them you can use security policies, antivirus software, firewalls, intrusion detection systems, and endpoint protection.
What are the three types of cybersecurity threats?
There are three types of cyber security threats that businesses may face: Information security, physical security, and virtual security. Information security threats are the ones that involve the theft of information or data. Examples of this type of threat include malware, viruses, data loss, and phishing. Physical security threats involve theft, loss, or destruction of physical assets. Examples of this type of threat include theft, robbery, fire, vandalism, and natural disasters. Virtual security threats are the ones that involve theft or loss of virtual assets. Examples of this type of threat include malware, viruses, and unauthorized intrusion.
