Network Security

Seemless network infrastructures.

Networking and Security work together like hand & glove, and must be in sync.

What is Cyber Security?

Cyber security is the practice of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. It's also known as information technology security or electronic information security. The term applies in a variety of contexts, from business to mobile computing, and can be divided into a few common categories.

  • Network security is the practice of securing a computer network from intruders, whether targeted attackers or opportunistic malware.
     

  • Application security focuses on keeping software and devices free of threats. A compromised application could provide access to the data its designed to protect. Successful security begins in the design stage, well before a program or device is deployed.
     

  • Information security protects the integrity and privacy of data, both in storage and in transit.
     

  • Operational security includes the processes and decisions for handling and protecting data assets. The permissions users have when accessing a network and the procedures that determine how and where data may be stored or shared all fall under this umbrella.
     

  • Disaster recovery and business continuity define how an organization responds to a cyber-security incident or any other event that causes the loss of operations or data. Disaster recovery policies dictate how the organization restores its operations and information to return to the same operating capacity as before the event. Business continuity is the plan the organization falls back on while trying to operate without certain resources.
     

  • End-user education addresses the most unpredictable cyber-security factor: people. Anyone can accidentally introduce a virus to an otherwise secure system by failing to follow good security practices. Teaching users to delete suspicious email attachments, not plug in unidentified USB drives, and various other important lessons is vital for the security of any organization.

 

The Scale of The Cyber Threat

The global cyber threat continues to evolve at a rapid pace, with a rising number of data breaches each year. A report by Risk Based Security revealed that a shocking 7.9 billion records have been exposed by data breaches in the first nine months of 2019 alone. This figure is more than double (112%) the number of records exposed in the same period in 2018.

Medical services, retailers and public entities experienced the most breaches, with malicious criminals responsible for most incidents. Some of these sectors are more appealing to cybercriminals because they collect financial and medical data, but all businesses that use networks can be targeted for customer data, corporate espionage, or customer attacks.

With the scale of the cyber threat set to continue to rise, the International Data Corporation predicts that worldwide spending on cyber-security solutions will reach a massive $133.7 billion by 2022. Governments across the globe have responded to the rising cyber threat with guidance to help organizations implement effective cyber-security practices.

Types of cyber threats

 

The threats countered by cyber-security are three-fold:

1. Cybercrimes includes single actors or groups targeting systems for financial gain or to cause disruption.

2. Cyber-attack often involves politically motivated information gathering.

3. Cyberterrorism is intended to undermine electronic systems to cause panic or fear.

So, how do malicious actors gain control of computer systems?

 

Here are some common methods used to threaten cyber-security:
 

Endpoint Security

What is meant by endpoint security?

Endpoint security is the practice of securing endpoints or entry points of end-user devices such as desktops, laptops, and mobile devices from being exploited by malicious actors and campaigns. Endpoint security systems protect these endpoints on a network or in the cloud from cybersecurity threats.

 

What is Zero Trust Security?

A traditional security model would assume anything inside your network is safe and can automatically be trusted. Zero Trust Security is a security method that considers all resources coming onto your network to be external and a potential threat that needs to be verified, even if they aren't. In today's remote, roaming, and mobile workers, resources, and devices inside the network hold just as much opportunity for compromise than ever. A Zero Trust Security approach helps secure access across your applications and network, giving you the visibility, you need to help reduce your attack surface. 

Trust nothing. When you consider your workforce, applications, and devices as resources where trust has to first be established, enforced, and continually verified, you make it harder for hackers to breach and attack your network.

 

What is Endpoint Security?

Endpoint security combines preventative protection with a new breed of continuous detection and response capabilities. Using cloud-based analytics, it eliminates bloated agents from consuming valuable CPU resources so employees can get their work done and businesses remain protected.

Endpoint protection systems are designed to quickly detect, analyze, block, and contain attacks in progress. To do this, they need to collaborate with each other, and with other security technologies, to give administrators visibility into advanced threats to speed detection and remediation response times.

How Does an Endpoint Security Solution Work?

An endpoint security solution includes continuous monitoring, rapid time to detection, and architectural integrations. With threats continually increasing in sophistication and frequency, it is more important than ever to deploy an effective endpoint solution.

Endpoint security solutions take a cloud-based approach to endpoint security to instantly access the latest threat intelligence without requiring manual updates from security admins. This allows for faster and more automated responses. They continuously monitor all files and applications that enter your network and can scale and integrate into your existing environment.

Cloud solutions offer scalability and flexibility and are much easier to integrate and manage. There is also less overhead since there is no infrastructure to maintain and the installation process is faster and simpler.

 

Types of Endpoint Security

Attackers stay up to date on security trends to create stealthier attacks, rendering legacy antivirus obsolete. Endpoint security combines the preventive protection of an EPP solution as well as the detection and investigative features of an EDR.

Endpoint protection platform (EPP)

 

An EPP solution is a preventative tool that performs point-in-time protection by inspecting and scanning files once they enter a network. The most common endpoint protection is a traditional antivirus (AV) solution. An AV solution encompasses antimalware capabilities, which are mainly designed to protect against signature-based attacks. When a file enters your network, the AV solution will scan the file to see if the signature matches any malicious threats in a threat intelligence database.

 

Endpoint detection and remediation (EDR)

An EDR solution goes beyond simple point-in-time detection mechanisms. Instead, it continuously monitors all files and applications that enter a device. This means EDR solutions can provide more granular visibility and analysis for threat investigation. EDR solutions can also detect threats beyond just signature-based attacks. Fileless malware, ransomware, polymorphic attacks, and more can be detected using EDR solutions.

 

Extended detection and response (XDR)

Where EDR improved on malware detection over antivirus capabilities, XDR extends the range of EDR to encompass more deployed security solutions. XDR has a broader capability than EDR. It utilizes the latest and current technologies to provide higher visibility and collect and correlate threat information, while employing analytics and automation to help detect today's and future attacks.

 

IoT Network (Internet of Things)

Does your wireless network support IoT Initiatives and their associated technical requirements?

IoT requires a secure and scalable network. As more devices and sensors come online, you'll want to ensure that you have plenty of capacity, end-to-end security, and traffic segmentation.
