Getting to Know the Network Security System
In understanding what a Security Consultant is, we need to first understand what a network security system exists in companies and industries.
What is Network Security
The task of a Security Consultant of course has responsibility for network security in a company.
Network security is a term used to define a system, security tool, or security policy designed to monitor, prevent, and respond to unauthorized network intrusions. The network security system will also protect digital assets which include network traffic.
Network security can be in the form of software or hardware designed to respond to various potential threats of cyber attacks that target the company’s internal network.
Network Security Types
In practice, this network security has various types. This is because the attacker has many methods that are increasingly varied. Following are some of the network security required for maximum network defense:
The internal network is designed to be used only by users in a corporate environment. Therefore you should have access control in blocking unauthorized users on your network.
Unauthorized users can be attackers who want to damage the network or steal confidential company data so that it can harm the company in terms of credibility and financially.
Antimalware software is software that protects your company from various malicious software such as viruses, ransomware, worms, and trojans. Then you should use an anti-malware that can continuously scan and keep track of malicious data on the network.
Applications that do not have this security system are often used by attackers to insert viruses or malware to access your network. By implementing application security you can protect any application related to network security.
This is one of the tasks of a Security Consultant which analyzes abnormal network behavior so that it can identify and prevent network anomalies in your company environment.
Data loss prevention
Every data that is in the company is important and confidential data. Therefore, this data should be stored in a storage area that prioritizes data loss prevention security.
Data loss prevention is a tool that can prevent sensitive data from being damaged or lost or misused by unauthorized users.
Email security is used to prevent e-mail from being intercepted from the company’s internal network. In practice, emails sent through the internal network are first sent via the internet, so email security is needed on your internal network to improve the security quality of the email.
Firewall acts as a barrier as well as a barrier for untrusted external networks to enter your internal network.
Security Consultants usually configure rules that define blocking or allowing traffic into the network.
Intrusion prevention systems
Intrusion prevention systems are tasked with analyzing traffic and data packets so that various types of attacks can be identified easily.
Virtual Private Networks (VPNs)
A VPN is a tool that can authenticate communication between a device and a network. This VPN creates an encrypted tunnel or tunnel to connect your device to the internet network. With a VPN you will be protected from hackers and attacks from external networks.
Web security helps prevent website-based attacks using the browser which is the main gateway to access your internal network.
Security information and event management (SIEM)
This SIEM functions as a tool that can assist Security Consultants in providing information about track records or activities that occur within the company’s IT environment. SIEM can identify and respond to threats in your network.
Not only the company’s internal network that needs to be given network security. However, your personal devices are also vulnerable to attacks when users access business networks. Endpoint security is needed to protect the network when connecting to remote devices.
Wireless technology is actually less secure when compared to wired networks. Therefore it is necessary to increase security to ensure that hackers do not easily access it.
Types of Network traffic has a variety of risk threats. Then Network segmentation can improve the network security system.
Types of Network Security Intrusion
There are several types of network security disturbances that need to be known, therefore Security Consultants will urge you to the following threats:
This hacking is the destruction of the existing internal network infrastructure.
Carding is a method of stealing data about a person’s banking identity. Usually, carding is done to steal someone’s credit card data to be used in online shopping.
Deface is a hacking method that changes the shape of the website he hacked.
This physing is a hacking method that falsifies official data so that it looks as if the user is using an official website so that it can steal all the user’s confidential data that is inputted into the fake website.
Computer Attack Classification
Talking about computer attacks, this can be further divided into various parts, including in terms of classifying them. Why should be concerned with this computer attack?
In fact, cybersecurity breaches are becoming more common than ever. With an average breach costing $3.62 million in damage, it’s no surprise that global companies are scrambling to secure their networks and prevent attackers from gaining access to their digital assets.
Therefore, here are some classifications of computer attacks that you need to know:
Cybersecurity attacks are becoming more sophisticated every day, with attackers able to hack, eavesdrop, scam and socially engineer their way into valuable corporate and customer data. While digital hacking incidents are on the rise, many IT professionals have lost focus on the tried and true methods of physical security attacks.
An organization can implement all the IDS, SIEM, and antivirus they want, but a firewall won’t stop someone from breaking down your door.
Physical security attacks can be dangerous as they bypass cyber security as well as digital controls.
Data and Media Security
Data and media security is very important. In this security, attackers will take advantage of existing weaknesses in the software that is applied to process data. Usually, the attacker will insert the virus on the target computer via an attachment to the e-mail. Another way is to install a backdoor or Trojan horse on the target system. Trojan horses are indeed the most unpleasant scourge when you have been exposed to the virus that causes some and and your media can be locked or stolen.
The goal is to get and collect information in the form of administrator passwords. This key will be applied to enter the administrator account.
Taking advantage of the element of weakness or carelessness of the person who causes it (has access rights) is one of the actions taken by a hacker or cracker to get into the way that is the target. This is commonly called social engineering. Social engineering is the highest level in the world of hacking or cracking.
Generally, people who do social engineering will disguise themselves as people who apply the method and forget the password, so they will ask the person who has access rights on the method to change or replace the password that will be applied to enter that method.
Safety in Operation
The last one is safety in operation. That is one procedure to limit everything related to post-attack security methods. Thus, the way things can go well or become normal again. Usually the attackers will delete all the logs that are left behind in the target method (log cleaning) after executing the attack.
Tips for Maintaining Network Security
When you know about various kinds of cybercrime attacks, now is the time for you to be more concerned about network security. Good network security will certainly make you calm with the data you have which can at least minimize cyber crimes. As such, securing your system should be at the top of your information security technician’s list.
Use Encryption On Wireless Access
With stolen credentials being the culprit in four out of five security breaches, it’s clear traditional usernames and passwords are insecure and unsuitable for today’s sophisticated hackers. Strong authentication is also referred to as two-factor authentication because you have to use two different things to prove your identity. It combines something you own, the authenticator (token, smart card, mobile app), with something you know, your login ID and password.
The use of passwords and IDs is very important so that not just anyone can connect to your wireless network access.
Change SSID Address
WiFi SSID, or WiFi Service Set Identifier, is the technical term for the name of your wireless network that you will see when connecting devices to your wireless home network. Hackers can use a password cracking tool, which uses the default and most common WiFi SSID, to easily find and take over your wireless network to steal sensitive data.
Use a unique WiFi SSID to distinguish your home network from other networks. The more unique, the better.
Turn Off Router Interface Features
Turn off login access for router management so that it cannot be accessed from outside. If anyone can enter the dashboard of this router, the infiltrator will easily read the log files on the router, to be safe, just turn off this feature.
How do you avoid getting caught by a virus? Definitely tighten your network by using antivirus. There are so many antivirus software that exist today, but it’s better if you buy a license so that security can be more thorough.
In addition, routinely back up your important data so that at any time if there is a problem, the data will still be in the backup. Will not know whether your network will be up to the virus or not, if it is up to the virus, then at least you still have the data that you have backed up.
In fact, not all computer network owners understand about network security systems. Even though it is like that, but somehow if the computer network is very important for his business, then inevitably there must be a way to understand all about computer networks including security issues.
The security consultant profession can be a trusted 3rd party to handle various problems regarding network security.
Security Consultant Specialist Profession
A security consultant, also sometimes called a security analyst, identifies vulnerabilities in computer systems, networks, and software programs and works towards solutions to strengthen them against hackers. This consultant role is a strong example of highly specialized IT work.
While many IT jobs are dedicated to departments within a company, security consultant jobs typically span multiple departments because of the large amount of data they have to protect.
As a security engineer, his job is to maintain and run the company’s security system. This may involve implementing and testing new security features, planning computer and network upgrades, troubleshooting, and responding to security incidents.
A security architect is a management-level individual who oversees the security of an organization’s network. These professionals are needed when the network is first designed, built, and implemented, and throughout the life of the network.
Its job is to monitor their organization’s network for security breaches and investigate if they occur. Use and maintain software, such as firewalls and data encryption programs, to protect sensitive information. Check for vulnerabilities in computer systems and networks.
Security Software Developer
As a security software developer, your job is to create new security technologies and make changes to existing applications and programs. They can also integrate security protocols into existing software applications and programs.
As specialized information security professionals, security auditors perform audits of computer security systems. They have knowledge of computers and information technology, plus expertise in cybersecurity, penetration testing, and policy development.
Chief Information Security Officer
The chief information security officer (CISO) is a senior-level executive within the organization who is responsible for establishing and maintaining the company’s vision, strategy, and programs to ensure information technology and assets are adequately protected.
Security Consultant Roles and Responsibilities
A security consultant focuses on protection, but their work varies. Ultimately, the job description involves implementing and executing a strategy for corporate or client cybersecurity.
Following are some of the assignments and responsibilities required of a consultant:
- Maximize efficiency in protecting data and information systems, networks and software from hacker attacks.
- Work closely with the IT department to fix specific online security issues.
- Work with managers, engineers, and other security analysts to reduce risks to the organization.
- Monitor and perform tests for system vulnerabilities.
- Supervise and mentor security teams of managers, engineers, and other technical or security employees.
- Plan and design security architecture for IT projects.
- Research cybersecurity criteria, security systems, and validation procedures.
- Investigate and provide security solutions that refer to standard business analysis criteria.
- Update and upgrade the security system as needed.
- Submit a formal report summarizing the test findings.
Security consultants have a primary responsibility involving helping organizations protect their IT systems from cyberattacks and unauthorized access. These professionals identify system vulnerabilities, develop security solutions, and ensure regulatory compliance.
So, computer network owners should be concerned about security. Security, of course, makes data that is personally owned which is confidential cannot be accessed easily by irresponsible and unauthorized people.
