By Tom Seest
At BestCyberSecurityNews, we help teach entrepreneurs and solopreneurs the basics of cybersecurity and its impact on their businesses by using simple concepts to explain difficult challenges.
With cyber threats becoming ever-more pervasive, it’s imperative to have an understanding of cyber security’s fundamentals. Learn the fundamentals of data protection, why it’s so essential, and how you can build your own cyber security program.
Cybersecurity refers to all processes and technologies designed to safeguard networks, devices, programs, and data against attack or unauthorized access – including firewalls, intrusion prevention systems (IPS), and data loss prevention (DLP).

A firewall is a device used to safeguard networks by controlling and regulating traffic from the public Internet. Firewalls play an essential role in providing network security and warding off cyber attacks from occurring against your infrastructure.
Firewalls provide networks with protection from unauthorized access and virus attacks that could quickly shut down operations and cause major disruption. Furthermore, they help identify any dangerous users or known bad actors.
Network switches can also help manage resources and control what data is accessible across a network, and monitor and control file and application execution so they only run when necessary.
As well as fulfilling their basic functions, firewalls also can detect and block outgoing data if they detect social engineering attacks or malware threats, restrict certain apps’ access, or limit user privileges on networks so that hackers cannot run scripts or macros that might compromise them.
There are various kinds of firewalls based on their structure and function, such as packet filtering firewalls, circuit level firewalls and network address translation (NAT) firewalls. Each has its own set of benefits and features to consider before selecting one for yourself.
Packet filtering firewalls inspect information packets at the transport layer of the TCP/IP protocol stack and evaluate them based on predefined rules that determine if they should be accepted or denied; these firewalls then discard them if any don’t meet them.
This type of firewall analyzes packets based on their source and destination addresses as well as application protocols involved with data transfer before making its decision on whether or not to allow the packet through.
Other types of firewalls, known as network address translation (NAT) firewalls, can transform different IP addresses into one unique address so multiple devices can connect to the Internet through one IP address instead of their individual ones; this keeps individual addresses hidden and makes it harder for attackers to identify them.

IPS solutions use various detection techniques to monitor network traffic in real-time and detect malicious activity, usually by comparing network packets against known threats or anomalies. Furthermore, some IPS systems also utilize machine learning technology for learning about attack patterns and recognizing threats.
Integral Protection Systems (IPSs) can protect critical networks by intercepting threats before they can reach their targets, protecting against data loss, and meeting industry regulations. They may also help improve network visibility while increasing efficiency for other security controls.
An intrusion prevention solution (IPS) may either be hardware or software-based. With hardware solutions using sensors to monitor network activity in real-time; or with software installed directly onto individual devices connected to a network.
These solutions can be used to detect unauthorized access and attacks on wireless networks, as well as delete malicious content after an attack occurs.
Your optimal network environment will determine which IPS type best meets the needs of your business. In general, for the strongest defense possible, an IPS is recommended to utilize both signature- and anomaly-based detection systems.
Anomaly-based detection compares random samples of network traffic against a baseline standard that defines what constitutes normal for any application or system. While this technique can identify new threats effectively, it can sometimes produce false positives when legitimate network activities exceed baselines, or they are improperly configured.
While both systems provide network traffic monitoring and protection, IPS systems are far more adept at protecting applications than IDS solutions due to their ability to recognize and track application behavior.
IPS solutions also have the advantage of taking action automatically, saving time for IT teams, and minimizing disruptions to normal operations. They can automatically block malicious IP addresses, reconfigure firewalls, or close ports in order to prevent future attacks from recurring, making IPS an invaluable component of any cybersecurity strategy.

Identification of critical networks is an integral component of cybersecurity, as data loss can have devastating financial, productivity, and reputational repercussions. According to IBM’s Cost of a Data Breach Report, average costs related to breaches will reach $4.2 Million by 2021.
Data Loss Prevention (DLP) software can assist your organization in identifying what data is critical, then take measures to protect that information from being lost, mishandled, or accessed by unapproved parties. DLP solutions encrypt files for added protection against unintended readers as well as block sensitive materials from moving outside approved locations or devices.
DLP systems also monitor user activity to prevent insiders from accessing sensitive data. They can detect suspicious activities like screen-capturing or copying/pasting to minimize data leakage.
DLP can assist your organization in complying with stringent regulations such as GDPR, which imposes heavy fines for organizations failing to abide by data protection and privacy laws. It can also classify and tag data to facilitate reporting and auditing processes more easily.
Some DLP solutions even feature encryption and isolation features to safeguard data in transit or at rest, enabling businesses to contain breaches while their investigations take place.
Integrating DLP as part of your cybersecurity strategy is crucial to creating an accurate view of where your data resides and which threats exist in its surroundings.
Effective DLP solutions monitor network traffic to detect any sensitive information that may pose a threat to your business, such as intellectual property, financial information, and any other sensitive files that could have an adverse impact on operations if compromised.
DLP software can also assist in monitoring your network for unauthorized actions, such as forwarding sensitive e-mails or uploading corporate files to consumer cloud services. When such actions are detected, DLP will deny access until the issue has been addressed.
DLP can be an invaluable asset in safeguarding sensitive data, but for maximum effect, it must be implemented as part of a larger cybersecurity strategy and regularly monitored. Your security team should work collaboratively with vendors and support teams to assess its implementation, configuration, and effectiveness within your environment.

An effective cybersecurity monitoring strategy is vital for organizations seeking to ensure the protection of their data and networks. A proper plan can help identify key networks as well as detect threats that may threaten its operations.
An important network can be identified by analyzing its overall performance, including the number of devices and applications connected. This information allows network administrators to detect issues before they become security breaches or degrade customer experiences.
Some network monitoring tools are capable of detecting applications and users that access the network without authorization, enabling IT to take measures to stop them from doing so again in the future – for instance, by implementing granular controls over what devices and users are accessing it.
Monitoring systems continuously and providing IT teams with tools to analyze the data will make it easier to detect issues quickly, taking corrective actions in time to decrease downtime and prevent the failure of systems. This approach also reduces costs related to broken systems.
An effective network security monitoring solution can detect early indicators of cyber or ransomware attacks, helping an organization respond rapidly and reduce damage caused by such attacks to its reputation, assets, and revenue streams.
Assessing network security requires taking into account how easy it would be for an attacker to gain entry and use of its resources, which will impact an organization’s ability to safeguard information, assets, and privacy for customers and retain customers as customers.
An organization can use cybersecurity monitoring to quickly identify crucial networks containing sensitive or confidential data, both internal and external systems that store or transmit it.
These types of networks should be regularly monitored to ensure they do not fall prey to hackers or any other type of attack and to protect both data and processes despite operating for extended hours. Regular monitoring can help keep data and processes safe even after hours.
