How to Protect Your Entire Network From Internet Attacks? Antivirus Software

cyberattacks usually aim to access, alter, or destroy sensitive information; Extorting money from users; Or boycott normal business operations.

Implementing effective cybersecurity measures is a huge challenge today as there are more devices than people, and attackers are becoming more creative.

What is essential in cybersecurity?

A successful cybersecurity approach has multiple layers of protection spread over the computers, networks, programs, or data that an individual intends to keep secure. In any organization, people, processes, and technology must complement each other to create a valid defense from cyber attacks.

Society

Users should understand the basic data security and compliance principles, such as choosing strong passwords, beware of email attachments, and data backup. Learn more about basic cybersecurity principles.

Processes

Organizations must have a framework for how they will deal with both successful and attempted cyberattacks. One well-respected framework can guide you. 

Technique

Technology is essential to give organizations and individuals the computer security tools they need to protect themselves from cyber-attacks. Three main entities must be protected: endpoint devices such as computers, smart devices, and routers; Networks; And the cloud.

45% of American companies have been hit by a hacker ransom note, but only 26% of those have their files unlocked - SentinelOne, 2018.

Why is cybersecurity important?

In today's connected WorldWorld, everyone benefits from advanced cyber defense programs. At the individual level, a cybersecurity attack can lead to everything from identity theft to extortion attempts, to the loss of essential data like family photos. Securing these organizations and others is vital to keeping our society functioning.

Everyone also benefits from the work of internet threat researchers, such as the 250th threat researchers team in Talos, who research new and emerging threats and cyber attack strategies. It reveals new vulnerabilities, educates the public about the importance of cybersecurity, and promotes open-source tools. Their work makes the Internet safer for everyone.

What is cybersecurity, and how can we mitigate cyber-attacks?

Malware protection

Malware,  short for malware, is a type of program that can compose a computer without the consent of the computer owner. Various types of malware can harm computers, such as viruses and Trojans. The term also includes other intentionally malicious software, such as spyware and ransomware.

Next-generation antivirus solutions

At a minimum, next-generation antivirus products should exceed signature-based detection performance while also incorporating some advanced technologies.

Most NGAVs bypass the use of indicators normalization (IOC) and metadata such as virus signatures, IP addresses, file hashes, and URLs. NGAV uses technologies such as advanced data science, machine learning, artificial intelligence, and data analytics to find patterns that attackers exploit.

NGFW -  Next Generation Firewall including Layer 

These types are; Such as an application firewall using Embedded Deep Packet Inspection (DPI) and Intrusion Prevention System (IPS). Other technologies may also be available, such as TLS / SSL encrypted traffic scanning, site filtering, QoS / bandwidth management, antivirus scanning, and third-party identity management integration (such as LDAP, RADIUS, and Active Directory).

DNS Security - Make it the first line of defense

Deployed as the default  DNS  caching layer all over your network, DNS Edge servers log every DNS query and response for every client on the system - no proxies are required. This means that cybersecurity teams gain insight into the intent of each device and can apply advanced intelligent analytics to identify patterns of malicious behavior such as data mining, tunnels, and domain-generating algorithms (DGA).

Portect your network

Protection and mitigation of advanced persistent threats

Advanced persistent threats  (APT) are sophisticated attacks, consisting of many different components, including hacking tools (spear-phishing messages, exploits, etc.), network deployment mechanisms, spyware, masking tools (root/boot sticks), and other technologies. The often complex, all designed with one goal in mind: undetected access to sensitive information.

APTs target any sensitive data. You don't have to be a government agency, large financial institution, or energy company to become a victim. Even small retail establishments have confidential customer information on the registry; Small banks operate remote service platforms for customers and businesses of all sizes, and they also keep payment information deemed dangerous in the wrong hands. For attackers, size doesn't matter: it's all about the data. Even small businesses are at risk of antipersonnel mines - and they need a strategy to mitigate them.

Multi-factor authentication

Multifactor authentication  (MFA) is an authentication method by which a computer user is granted access only after one or more evidence (or factors) has been successfully submitted to the authentication mechanism: knowledge (something only the user and the user know), possession (something the user and the only user has) ), And inheritance (user and user only thing).

MFA is most often used in Edge or Network Environment, but it can also be used within it to protect valuable data and resources.

NAC - Network Acceptance Control

NAC aims to control traffic, precisely what the name suggests - controlling access to a network with policies, including endpoint security policy checks before acceptance and post-acceptance controls about where users and devices can enter on the system And what they can do.

WAF - Web Application Firewall

A  web application firewall  (or WAF) filters and screens and blocks HTTP traffic to and from the web application. A distinction is made between WAF and a regular firewall as WAF can filter the content of specific web applications while appropriate firewalls act as a security gateway between servers. By scanning HTTP traffic, it can prevent attacks caused by security flaws in the web application, such as SQL injection and cross-site scripting (XSS), file insertions, and misconfigured security configurations.

Face gateway internet solution

A secure web gateway is a security solution that prevents unsecured/suspicious web traffic from entering or exiting an organization's internal corporate network. Companies deploy the Secure Web Gateway to protect their employees from malware-infected web traffic to fight threats emerging from the Internet. It also enables enterprises to comply with the organizational policy of the organization. It features URL filtering, data leakage prevention, virus/malware code detection, and application-level control.

Clear vulnerabilities

A  vulnerability scanner is a computer program designed to evaluate computers, networks, or applications for known vulnerabilities. In plain words, these scanners are used to discover the shortcomings of a specific system. It is used in identifying and discovering security vulnerabilities arising from misconfigurations or defective programming within network-based assets such as firewall, router, web server, application server, etc.

Audit and control

You must know at any time what is happening with your network and devices. There is a need for a tool to automatically discover and connect everything you need to know about your network infrastructure, the monitoring, alerts, and graphs you need to maintain high availability. At the beginning of each project, we will carry out a  review to have a visionary knowledge of the environment to provide the client with the best solution.

All flavors of VPN (Secure Tunnel)

A  virtual private network  (VPN) extends a private network across a public network. It enables users to send and receive data over shared or public networks as if their computers were connected directly to the private network. Thus, applications running on a computing device, such as a laptop, desktop, and smartphone, via a VPN, may benefit from the functionality, security, and management of the private network. Encryption is common, albeit not an integral part of a VPN connection, and provides integrity.

Companies often use VPN service for remote / satellite offices, remote users (Home Office), third-party companies they do business with, and even internally to secure vital data. We support all types of VPN

Intrusion prevention systems

An  Intrusion Prevention System  (IPS) is a device or software application that monitors a network or system for malicious activity or policy violations. Usually, any malicious activity or breach is either reported to the administrator or centrally collected using the Security Information and Event Management System (SIEM), or attempted to block/stop it. The SIEM system combines output from multiple sources and uses alert filtering techniques to distinguish malicious activity from false alarms. Our view is that IPS should be installed at the edge of the network, but also at the access layer to monitor and block unencrypted traffic.

Provides network security at all seven layers of OSI

Above we presented several ways to secure your network environment, applications, and data. All of these puzzles are essential and provide a strong and secure infrastructure. Network security must be implemented at all layers of the OSI model:  application, display, session, transport, network, data link, physical.  Threats are constantly evolving, and we can help you keep your systems safe and up to date.

Types of cybersecurity threats

Ransomware is a type of malware. It is designed to extort money by blocking access to files or the computer system until the ransom is paid. Payment of the amount does not guarantee data recovery or system restoration.

Social engineering is a tactic used by adversaries to trick you into revealing sensitive information. They can request cash payments or access your confidential data. Social engineering can be combined with any of the threats mentioned above to make you more likely to click on links, download malware, or trust a malicious source.

Phishing is the practice of sending fraudulent emails that resemble emails from reputable sources. The goal is to steal sensitive data like credit card numbers and login information. It is the most common type of cyber attack. You can help protect yourself with education or a tech solution that filters malicious emails.

Effective Mitigation Strategies: Some Examples

No ICT infrastructure can be 100% secure, but there are reasonable steps that every organization can take to drastically reduce the risk of cyber-infiltration. Through a comprehensive and detailed analysis of local attacks and threats, the Australian Signal Directorate (ASD) found that four basic strategies can mitigate at least 85 percent of the targeted cyber intrusions it responds to:

Use an app's whitelist to help prevent malware and unapproved software from running

Debugging applications such as Java, PDF and Flash viewers, web browsers, and the Microsoft Office

Corrected vulnerabilities in the operating system

Restricting administrative privileges to operating systems and applications, based on user duties

These steps are very helpful: Recommended to all Australian government agencies. Based on Kaspersky Lab's deep experience and analysis in the field of combating APT, we believe that this approach will be beneficial not only for government agencies or large organizations but also for smaller businesses.

summary

We have demonstrated a variety of technology options to secure your network environment. In our opinion, good habits are essential, and try to implement them in your environment. It might not be easy to do them all at once, but try doing it step-by-step. Not a revolution, but an evolution.
