Community safety refers to all of the practices and software program utilized by companies to guard the integrity, confidentiality and accessibility of their digital belongings. It ensures that your knowledge stays protected against completely different safety threats similar to malware and knowledge breaches.
Groups using the fitting community safety measures can anticipate uninterrupted providers whereas stopping unauthorized entry and data theft.
Given the evolving and numerous nature of cyber assaults, manufacturers have to make use of completely different sorts of protecting measures to save lots of themselves from such vulnerabilities.
On this article, we’ll take a look at 5 kinds of community safety measures and perceive how they will safeguard your group’s digital infrastructure.
1. Firewalls
Firewalls are like safety guards on your community site visitors. They take a look at the incoming and outgoing site visitors out of your techniques and monitor them primarily based on a set of predefined guidelines. If a request appears to originate from an untrusted supply, a firewall prevents it from going by means of.
They examine every knowledge packet that enters or exits the community by its supply and vacation spot tackle, port, and protocol. This ensures that solely authentic requests are processed and accepted.
In style sorts of firewalls embrace:
- Packet-filtering firewalls: Study the packet primarily based on easy guidelines however don’t take into account context.
- Stateful inspection firewalls: Observe lively connections and make selections primarily based on the well being of that connection.
- Hybrid mesh firewalls: Combines a number of firewall varieties to safe your community. A hybrid mesh firewall is often leveraged in complicated and distributed environments.
- Proxy firewalls: Act as intermediaries between the tip consumer and the community. It inspects the site visitors on the utility degree.

2. Intrusion prevention techniques
An Intrusion Prevention System (IPS) always displays the community site visitors, identifies suspicious site visitors, and takes speedy motion to dam or mitigate dangers. Not like intrusion detection techniques (IDS), which alert admins about potential threats, IPS takes proactive motion.
It makes use of signature-based detection to establish recognized assault patterns and anomaly-based detection to identify uncommon or suspicious actions. As soon as a menace is recognized, the IPS can take numerous actions, similar to blocking site visitors from the supply and resetting a community connection.
IPSs are efficient at stopping a variety of threats:
- Malware: Stops the unfold of malicious applications like viruses and worms.
- Denial of Service (DoS) assaults: Prevents threats that purpose to overwhelm and disable community sources.
- Exploits: Blocks try to benefit from current vulnerabilities in techniques and functions.
- Brute power assaults: Detects repeated failed login makes an attempt and halts unauthorized entry efforts.
3. Information loss prevention
Information Loss Prevention (DLP) prevents delicate organizational knowledge from being misplaced, leaked, or accessed by unauthorized customers. Firms want it to defend confidential data, adjust to laws, keep away from monetary penalties, and preserve their status.
It secures knowledge each in transit and at relaxation, guaranteeing the information stays safe always.
DLP options safe networks by monitoring and controlling knowledge movement throughout networks, endpoints, and cloud environments. Every serves distinct functions:
- Community DLP: Displays knowledge in movement throughout the community and prevents unauthorized sharing of delicate data.
- Endpoint DLP: Protects knowledge on particular person gadgets similar to laptops, workstations, and smartphones by controlling file transfers and exterior storage utilization.
- Cloud DLP: Secures delicate knowledge on distant servers and cloud functions, guaranteeing each safety and compliance.
They examine the content material and context to acknowledge protected knowledge and apply pre-defined guidelines to cease violations.
When a breach is detected, a typical DLP system can take many actions together with encrypting the information, blocking file switch, or alerting the directors.

4. Community entry management
The Community Entry Management (NAC), because the title suggests, regulates the place the information or functions could be reached. It ensures that solely licensed customers can entry the organizational knowledge on compliant gadgets.
This community safety measure prevents the connection of an unapproved system to make sure the safety and security of personal knowledge.
Directors will first have to grant entry to customers and authorize their gadgets. When the consumer makes an attempt to attach with the community, the NAC will confirm the credentials. If handed, the consumer can entry the related knowledge.
On the flip aspect, if the credentials don’t match, the NAC can block, quarantine, or restrict the consumer’s entry to the information. The admins can set guidelines for this primarily based on their organizational wants.
NAC options usually use applied sciences like role-based entry management, endpoint safety assessments, and multi-factor authentication to strengthen safety. These applied sciences improve safety, preserve compliance, and enhance productiveness (by way of automation).
5. Community segmentation
Community segmentation is the method of breaking a community into small items. Within the occasion of a breach or knowledge corruption, every of those items might be remoted to include the injury.
Furthermore, this additionally improves the efficiency of every of the subnetworks, guaranteeing the operations proceed as ordinary.
Safety groups can create boundaries between completely different elements of the community to create these community segments. The three widespread methods to try this embrace:
- Bodily segmentation: Use separate bodily gadgets, like switches and routers, to create boundaries to separate networks.
- Logical segmentation: Create separate community segments utilizing software program referred to as digital LANs (VLANs). This improves effectivity and reduces value as you possibly can handle a number of remoted networks on a single infrastructure.
- Micro-segmentation: The separation occurs on the utility or workload degree. It’s carried out by isolating the site visitors between particular person gadgets or providers. Specialised software-defined networking (SDN) to implement safety insurance policies.

Wrapping up
The state of cybersecurity in 2024 requires organizations to make use of multi-layered community safety measures to deal with the big variety of digital threats.
Firewalls are the primary line of protection that filters the site visitors and blocks unauthorized entry. IPS actively displays the community exercise throughout operation to detect and cease assaults. DLP displays and prevents the unauthorized sharing of delicate data by limiting entry instantly.
NAC solely ensures that licensed customers from compliant gadgets can entry organizational data. Lastly, community segmentation breaks the community into smaller segments, permitting the admins to restrict the unfold of assaults or corrupt non-public knowledge.
All the safety measures work collectively to assist companies and enterprises defend their and their clients’ knowledge. Organizations can leverage them to reduce vulnerabilities and safeguard their priceless data.
