22 Ways You Can Stay On Top Of Your Network Security
What is Network Security?
Cybersecurity is the practice of protecting your network and its integrity from potential threats. By using hardware and software solutions to manage network access, your company's cybersecurity must identify threats and prevent them from accessing systems. Therefore, cybersecurity is not concerned with managing specific devices, but with how those devices communicate and interact with each other.
No matter how small your business is, it’s important to identify/implement the following in your small-to-medium business’s network security so that measures can be properly implemented:
Network Security Threats
Cybersecurity threats can come from both inside the company (employees use their access to harm the company) and outside the company (hackers try to steal your data). These threats can also be the result of inadequate protection and human error or oversight (such as opening an unknown email and clicking on the attachment, which then downloads malware to your computer).
Network Security Goals
Depending on the type, size, and complexity of your business, the details of your cybersecurity goals will differ from those of other small and medium-sized businesses, even within the same industry. Clarify and outline your cybersecurity goals, focusing on which areas need better protection and taking into account any past breaches. For example, a company whose network has been compromised may want to improve the security of employee passwords, configure mobile device management so that compromised devices cannot join the network, and separate the main and guest network servers.
Network Security Plan
You can now create a cybersecurity plan that will address the areas highlighted in the cybersecurity goals you have established for your company. This should include indicating the specific roles that employees will play during the implementation of these procedures (for example, human resources, team leadership, and IT) and whether the changes will be made internally or outsourced to an external IT team.
Network Security Policy
You should now have the knowledge and framework to begin creating a cybersecurity strategy for your business. This requires outlining the rules for computer network access, determining how the rules and regulations will be enforced, and outlining the details of basic corporate security procedures and the cybersecurity environment.
If you feel a little overwhelmed going through these processes, let ANHC IT do the heavy lifting for you so you don't have to lift a finger when it comes to cybersecurity.
Why Is Network Security Important?
Without effective cybersecurity, your data is essentially open to theft. Cybercrime is on the rise and cyber threats are becoming more sophisticated and cunning. Even with the most basic network security, you can effectively block a large number of malware, viruses, and hacker attacks. Overall, cybersecurity is critical to preventing data breaches that can cause enormous damage to your company's reputation and finances.
Let’s have a look at the different elements involved with network security:
1. Access Control
Allowing all users full access to the entire work network is a mistake many startups make. Restricting and managing network access is an important part of network security. Remember, each user only needs access to the applications, folders, and files that they directly use to do their work.
Identify users and devices and ensure that each new user and device follows the correct policies and procedures so that they and their devices are recognized. Security policies must be created that cover the different types of devices that access the network. Therefore, you can enforce who has approved access and block access to the unrestricted network or to any unidentified user or device. You will often hear this process referred to as Network Access Control (NAC).
The different network security controls are as follows, with access control falling under administrative controls:
2. User Identity Management
Identity management, simply put, is the operation of controlling user information on a computer. This includes what information authenticates the user, as well as information that indicates the resources and actions they have access to.
Define and manage user roles and their access to sensitive networks and data. This applies to both customer and employee identities. With one digital identity per user, you can easily manage and monitor each person and their activities. As briefly mentioned above, users within a company often accumulate more access than they need to do their jobs. The more access a user has, the greater the chances of a data breach occurring.
3. Anti-Malware
Anti-malware software is another essential element of any company's cybersecurity. Antivirus and antimalware software should be part of your network security to detect and contain viruses, worms, ransomware, spyware or Trojans that try to attack your system. A deep understanding of network-level threats is an indicator of excellent anti-malware protection.
A good malware detection program will not only detect incoming malware, but will also continuously monitor and crawl files for anomalies. This is crucial, as you can't rely on protection alone: you also have to take human error into account.
With the integration of artificial intelligence and machine learning, modern anti-malware tools have become better at anticipating and responding to new and evolving threats. These advanced technologies enable proactive and adaptive security measures, providing enhanced protection against sophisticated malware attacks that may go undetected by traditional methods. Implementing an anti-malware solution equipped with artificial intelligence capabilities ensures a more dynamic and robust defense against various cyber threats.
4. Application Security
Application security is a broad spectrum that covers the hardware, software, and processes you choose for optimal security measures. Having insecure applications is one of the main reasons why companies are targeted by hackers: data can easily be leaked through insecure applications that are not supported by corporate network security.
It is important to take care to protect all the applications and software you use in your business. This applies to both internally created programs and purchased programs. All applications are suspected of having vulnerabilities that are frequently exploited by attackers to gain unauthorized access.
In recent years, the concept of DevSecOps has received increasing attention, emphasizing the integration of security practices into the software development lifecycle. This approach involves incorporating security measures from the initial design phase through development, testing, deployment and maintenance, ensuring that security is an integral and continuous part of the process and not an afterthought. Adopting a DevSecOps framework can significantly reduce the risks associated with insecure applications, resulting in a more resilient and secure operating environment.
5. Hardware Security
Hardware security is another component that complements software security and cannot be ignored when placed next to its technical counterpart. Unlike antivirus applications, hardware security describes the physical hardware devices that provide protection against vulnerabilities. Devices that provide additional protection for your network include hardware firewalls and hardware security modules.
Hardware security modules are physical computing devices used to protect computer hardware. It also provides cryptographic processing (via one or more cryptographic processing chips) and manages digital keys. This means strong authentication. Traditionally, modules come in the form of plug-in cards or external devices where they can be connected directly to a computer or network server.
6. AI-Based Threat Protection
Many threat detection tools now use artificial intelligence to increase their effectiveness. These AI tools can predict external threats in advance and detect breaches when they occur. They can also respond to ransomware or malware attacks. These predictive and automated responses will undoubtedly have a huge impact on cybersecurity.
Artificial Intelligence (AI) is leading the current wave of digital transformation. Companies large and small are actively expanding their AI footprint. Executives have been developing a more complete understanding of what artificial intelligence is and how to use it to their advantage in business. Companies are using artificial intelligence to gain insights into the data they collect, allowing them to engage with customers and differentiate themselves from the competition.
Advances in artificial intelligence in threat detection now employ machine learning algorithms that can analyze patterns and learn from them to provide more sophisticated protection. This includes identifying network behavioral anomalies that can bypass traditional security measures. Integrating machine learning allows AI systems to adapt and improve over time, improving their ability to detect new and evolving threats. Additionally, AI-powered threat intelligence platforms are increasingly used to collect and analyze threat data from various sources around the world, providing real-time insights and enabling more proactive cybersecurity measures.
7. Email Security
Email portals represent a significant breach risk and are the primary way corporate data is compromised. Many attackers target emails with phishing attempts and malware links. They collect personal information to present convincing emails and deceive recipients.
Email security (typically through an email security application) is essential for blocking incoming attacks and managing outgoing messages. Phishing attacks continue to gain sophistication, and tactics like business email compromise (BEC) are becoming more common. These attacks often involve impersonating a trusted executive or partner to request confidential information or financial transactions.
Employee training is also important here, because if the recipient of the virus does not open an infected link or pop-up window, the computer will not become infected. Regular training and awareness programs are critical to keeping employees up to date on the latest phishing techniques and best practices for identifying and reporting suspicious emails. This human layer of security complements technical measures to form a comprehensive defense against email-based threats.
8. Network Security Firewalls
Firewalls are an important part of any organization's network security. They provide a hard barrier between your trusted internal network and untrusted external networks, like the Internet. You define rules to determine what traffic the firewall allows and what traffic is blocked.
As a standard security tool in most businesses, you probably have a traditional firewall in your business. However, in today's ever-changing threat landscape, next-generation firewalls (NGFWs) need to be considered to provide adequate protection. NGFWs take a better step forward by offering “deep packet inspection” that goes beyond port/protocol inspection and blocking. They add application-level inspection, intrusion prevention, and provide intelligence from outside the firewall.
These advanced firewalls examine the content of your traffic in detail, allowing them to detect and block sophisticated cyber threats. They also integrate seamlessly with other security systems, providing a more comprehensive and adaptable approach to cybersecurity. Capabilities such as application awareness and control, advanced threat protection, and automated responses to identified threats are a critical part of NGFW's modern network security strategy. Their ability to provide real-time, context-aware security makes them an important component in defending against the increasingly sophisticated and targeted cyberattacks we see today.
9. Intrusion Detection and Prevention
Intrusion detection software monitors your network for suspicious or malicious activity by scanning network traffic. The software flags this activity and typically sends the results directly to one or more administrators. It can also be collected in security information and event management (SIEM) systems.
Intrusion prevention systems (IPS) block any incoming attack before it is executed. They often use artificial intelligence to predict and identify threat patterns. IPS continuously monitors your network for potentially malicious activity and captures information about these events.
10. Mobile Device Security
When you think about cybersecurity, don't forget to include the mobile devices and applications that cybercriminals are increasingly targeting. There are several mobile device management software and mobile applications available today. You can even use Office 365's built-in mobile device management. With these, you can manage your devices and keep them safe.
Every year, more and more companies support enterprise applications on personal mobile devices. Of course, devices with network access must be controlled and monitored. The connection must also be configured to keep network traffic private. It is necessary to implement mobile device or mobile application management systems and procedures.
11. Wireless Security
The security of wireless networks must be stricter and more professional than that of wired networks. This is because wireless networks are inherently less secure. Without strong and effective security, installing a wireless LAN is like putting Ethernet ports everywhere, allowing people to access your network without even knowing who they are.
To prevent your network from being exploited, you should take advantage of specialized products that protect your wireless network and steps you can take to ensure you are protected against the risk of an attack. This includes strong encryption, strong WPA passwords (different for guest networks, if applicable), checking for unauthorized WIFI access points, hiding network names, using a firewall, enabling MAC authentication, and using a VPN.
12. Cloud Security
As more and more cloud services emerge, the use of cloud security becomes essential. This is different from security solutions provided by the cloud. It refers to securing the cloud itself to run applications, process transactions, and store data securely.
High-profile hacks in recent years have made business owners nervous about storing data in the cloud. However, in almost all cases, it is the way the cloud is used, not the cloud itself, that causes problems.
Here are five key ways to secure your cloud data:
13. Virtual Private Networks (VPNs)
A VPN encrypts the connection from the endpoint to the network. Most of the time this happens on the Internet. Typically, remote access VPNs use IPsec or Secure Sockets Layer to authenticate device and network communications.
Currently, VPN is a fairly mature cybersecurity tool. When your online activities are not protected, anyone can easily view them. Enter VPN. It works by encrypting your data and routing your connection through a private server. Therefore, your activities and privacy are protected online.
14. Network Segmentation
When everything is combined, it's easy to see how difficult it can be to manage your network security. Network segmentation divides your network traffic into different categories. This makes it easy to apply different security policies based on the identity of the endpoint.
These classifications should be based on the identity of the endpoint, not the IP address. Access can be assigned based on role, location, etc. This ensures that the correct level of access is assigned to the right person and that suspicious devices are flagged and contained so that compromised situations can be remedied.
15. SIEM software
Security information and event management (SIEM) is a software solution that aggregates and analyzes the activity of many different resources in your IT infrastructure. SIEM collects security data from network devices, servers, domain controllers, and more.
SIEM products bring together the information IT teams need to identify and respond to threats. These products come in many forms, including physical and virtual devices, as well as server software.
16. Behavioural analytics
Behavioral analysis in cybersecurity is loosely defined as the use of software tools to detect unusual patterns of data transmission on a network. In theory, analytics tools would detect anomalies and alert IT managers, who would prevent anomalous behavior or cyberattacks.
Companies use behavioral analytics to detect intrusions that evade prevention technologies such as firewalls, intrusion prevention systems, and antivirus software. These traditional tools compare fingerprints or signatures identified in previous attacks, while behavioral analysis tools study and report judged anomalies against a baseline of normal behavior.
17. Data Loss Prevention (DLP)
Data loss prevention (DLP) is a tactic used by companies in their network security policies to ensure that users do not send sensitive information outside the corporate network. DLP also refers to software products that help network administrators control what data end users can transfer, copy, etc.
Humans will always be the weakest security link in a company. Technology and processes need to be implemented to ensure that employees do not, intentionally or unintentionally, send sensitive data outside the network.
18. Web security
Implement a web security solution to monitor employee web usage, block web-based threats, and deny access to malicious websites. This will protect your web gateway on-premises or in the cloud. Cybersecurity also refers to the measures you take to protect your company's website.
The security of your website or web application is greatly affected by the level of your protection tools. Some of the major vulnerabilities of web-based services (the most common way to hack a website or web application) include SQL injection, password disclosure, cross-site scripting, data leak, remote file inclusion and code injection.
19. DDoS attack security measures
A distributed denial of service (DDoS) attack occurs when multiple infected computer systems attack a target, resulting in a denial of service to users. The target can be a server, website, or other network resource. Make sure programs and software are kept up to date. This will ensure that any errors or issues are flagged and fixed as they arise.
Carefully plan and implement security measures to prevent DDoS attacks. The first thing to keep in mind is that a DDoS attack can happen to anyone; Thinking it can't happen to your small or relatively unknown business will only do you a disservice and make your business more vulnerable to attacks. There are a number of measures you can use to protect your business from DDoS attacks, including: developing a plan, assigning roles, and installing protection tools such as firewalls, network monitoring software, antivirus and antimalware programs, and threat monitoring systems. .
20. Endpoint Security
In network security, endpoint security is the protection of enterprise networks when accessed by remote devices. Such devices include laptops, cell phones, and iPads. Every time a new device connects to a network, it creates a potential entry point for security threats.
In an era of BYOD in the workplace, and when employees try to access work files using public networks (like in libraries or airports), it has never been more important to think about how endpoint security influences your overall strategy. network security.
21. Zero Trust Architecture
Zero Trust is a security strategy focused on the idea that organizations should not automatically trust anything inside or outside their perimeter, but rather should verify everything connected to their systems before attempting to grant access.
This approach is increasingly important given current cyber threats and the shift toward remote work.
The implementation of Zero Trust implies a change in the philosophy of cybersecurity. Traditionally, cybersecurity has focused on strong perimeter defenses to stop threats. However, once on the network, users and devices typically have considerable access. Zero Trust eliminates this implicit trust and requires continuous verification of every user and device, whether they are inside or outside the network perimeter.
Key components of zero trust architecture include:
· Strict User Authentication: Verifying the identity of all users before granting access to network resources.
· Micro segmentation: Breaking up security perimeters into small zones to maintain separate access for separate parts of the network.
· Least Privilege Access: Limiting user access rights to only what is strictly necessary for their role.
· Multi-Factor Authentication (MFA): Requiring multiple methods of verification.
· Regular Monitoring and Validation: Continuously monitoring network activity and validating security configurations.
Adopting Zero Trust can be complex, involving significant changes in network architecture and policy. However, its benefits in reducing the risk of data breaches and cyberattacks make it a compelling approach for modern network security.
22. Cyber Security Insurance
Cybersecurity insurance is a product that businesses can use to protect themselves from the financial risks associated with digital threats and data breaches. Today, this has become an important consideration for businesses of all sizes.
Cybersecurity insurance policies typically cover a variety of event types, including data breaches, network damage, and business interruptions caused by cyberattacks. This helps reduce the financial impact of incidents such as ransomware attacks, data theft and other forms of cybercrime.
Key aspects of cyber insurance include:
· Risk Assessment: Many insurers provide risk assessment services to identify vulnerabilities and improve security practices.
· Cost Coverage: Policies may cover costs related to legal defence, customer notification, data recovery, and even ransom payments in some cases.
· Support Services: Insurers often offer support services during and after a cyber incident, such as legal advice, public relations, and cyber security expertise.
It’s important to note that cyber security insurance does not replace the need for robust security measures. Think of it more as a safety net, providing financial support and resources in the event of a security breach.
