Cyber Security Checklist For Business Organizations

On June 25, 2022

Cyber security is a vast and dynamic domain. As new cyber security challenges emerge rapidly, it may become overwhelming for business organizations to keep up. To combat this, business organizations should implement a cyber- security checklist. A comprehensive cybersecurity checklist assists firms in adopting a cybersecurity-focused workplace culture as well as strengthening their cybersecurity posture for complying with various regulations.

1. Communications channels to be encrypted

Spam filtering technology in email servers automatically detects and eliminates emails that look to be phishing scams from employees’ inboxes. When communicating work-related information and passwords, use an encrypted email or messaging service to reduce the likelihood of the communication being intercepted and decoded. Employer-issued devices should never be linked to a public network. Also when viewing websites, employees should use security mechanisms and protocols.

2. Decentralize your cybersecurity strategy

Allowing the CISO to control and oversee user rights can help prevent specific departments from getting access to information they don’t need. Organizations that provide identical rights to all users are more prone to attacks.

3. IT strategies must be separated from Cybersecurity strategies

Cybersecurity threats are increasingly complicated and incident reaction times are more rapid. At the company level, the CISO should evaluate cyber threats and build mitigation and response plans.

4. Effective and efficient incident response process

An incident response strategy can assist staff in detecting, responding to, and recovering from cybersecurity problems with more efficiency. The incident response rules should be followed by all organizations. The strategy should spell out how to document and respond to cyberattacks.

5. End-user cybersecurity awareness training

A single mistaken click on a phishing email by distracted or anxious personnel might disclose vital information. Employees should be taught not to read emails from unknown senders or click links inside them. Leadership should be notified of any possible phishing assaults.

6. Implement ZTNA

The Zero Trust Network Access security paradigm is intended to instill in an organization’s culture a “never trust, always verify” mentality. By default, network administrators and IT employees are instructed to deny access to all devices in this cybersecurity architecture. Two-factor authentication is encouraged by a Zero Trust policy.

7. Strong and complex credentials

Passwords must be made up of a random sequence of alphanumeric and special characters. Also, store encrypted passwords only.

8. Automated updates and upgrades

Updates to operating systems are frequently applied to mitigate or eliminate vulnerabilities in older versions. Malicious software created for a certain version of the operating system will be discovered and deleted by the operating system in a future update when devices are upgraded. Antivirus software may be programmed to update automatically whenever a new version is published, improving the likelihood of protection from malware and other sorts of cyber-attacks.

9. Data backups

Employees must be able to restore their data from previous save points if their hard disk has to be reset. IT department should be in charge of data backups, and backup logs and tests should be performed regularly.

10. Access to critical systems to authorized security personnel only

No employee should be able to make changes to the company’s network and devices’ system details and configuration. Security threats are addressed by reducing the number of network administrators. Auditing and removing accounts from employees who have transferred workstations or are no longer employed by the company is another great practice.

11. Activate automated locking features

This stops onlookers from seeing what is displayed on the gadget. Users can remotely access the computer when it is logged in, which is why it should not be used unless it is under the direct supervision of an employee.

12. Device disposal and data-purge

When sensitive data is no longer needed, it should not be discarded. To delete all data from the hard disk, it should be entirely formatted. Any linked data may be entirely retrieved via a SATA connection without the hard disk being physically destroyed. Before destroying the drive, make sure the data on it is backed up.

13. Periodic cybersecurity evaluations and assessments

To identify new hazards, systems and software should be reviewed regularly. Some upgrades may cause systems to malfunction or expose them to risks. When evaluating a network, it’s essential to talk to an impartial cybersecurity professional who can give knowledgeable suggestions.

14. Employ 3rd-party security services

Leaders across organizations are advised to leverage the services from MSSPs (Managed Security Service Providers) to strengthen the cybersecurity posture of their organizations.

In Cybersecurity

The use of IT and cyber technology in business operations is expanding. As a result, the number of phishing attempts on enterprises has also skyrocketed. In the fight against cybersecurity attacks, inadequate cybersecurity awareness training continues to be a major issue for businesses.

Firms are recommended to take following proactive measures to stay protected against cyberattacks:

Identifying cybersecurity risks: Workplace culture, people profiles, job tasks, and other variables can impact risk factors.
Educating employees: Commit to a range of methods for keeping employees informed about cyber security attacks and what they can do about it. This necessitates a mental shift: instead of perceiving the person who opened the phishing link as the center of failure, recognize that the security and training framework surrounding that individual has failed.
Invest in reducing Cybersecurity risks to strengthen the overall security posture: Change has to start from the top. Put a monetary value on everything, from the cost of losing access to mission-critical data to the risk of being held liable for losing consumer information.
Avoiding social engineering assaults using employee training: Social engineering strategies include sending questionnaires to employees and encouraging them to provide personal information. Appropriate training will help employees to identify if they are being targeted.
Practice thwarting social engineering attempts right from their onboarding phase: Several social engineering attack scenarios must be simulated, and the employee must be tested as a result. From the initiation phases, password security, phishing, and social engineering assaults must all be addressed. Most importantly, employees have to not only understand the compliance and regulations but also why the best practices are so vital.
Rewarding employees motivate them: Giving out rewards for detecting genuine network attacks and weaknesses is an excellent illustration of this.
Evaluating employee security awareness: Corporate assessments and committee meetings have the unexpected effect of improving cybersecurity awareness.
Trust & encourage open communication in work culture: Employees should not be hesitant to report system issues. They should be encouraged to share their knowledge with others. If everyone is on the same page, it will be much easier to raise awareness about cybersecurity issues.
Discuss about updates and news in Cybersecurity domain everyday: Employees must pay attention to latest developments at cyber security front. Make sure employees are informed about any new crypto-malware or exploits that might cause phones or devices to crash with a single message.

How to plan a curriculum that trains employees to reduce cybersecurity risks?

Employee cyber security awareness training plan must include the following aspects:

Phishing emails that are dummy; just to check employees’ alertness levels
Blog articles, workbooks, documents for self-learning and updating themselves
E-learning that is customized as per the business, sector, and vertical requirements
Quizzes and short questionnaires to check the skills evaluating employees’ security awareness

Each of these characteristics helps employees have a better understanding of how security methods and tactics work, as well as how security mishaps might develop.

How does training employees with security awareness reduce cybersecurity risks to businesses?

Cybersecurity awareness training benefits stakeholders across the business in the following ways:

Increasing the cyber-resilience of the organization
Helping develop a security-conscious workplace culture
Taking steps to reduce human error and solve the security problems
Increasing audit findings and demonstrating regulatory compliance
By generating a yearly, bi-annually, and quarterly schedule of events, detecting areas of overlap, and recognizing user weariness, corporations save time and money when planning a security awareness campaign.

Cybersecurity awareness training should begin at the outset of a company and not be hurried. Before starting their new positions, employees and candidates must complete network security training to guarantee that they understand how to use technology and stay secure online. It’s not enough to be aware of dangers; you must actively seek out and monitor them. Users must be educated and informed about network security methods and solutions to get the most out of them. It’s more important for digital and e-commerce businesses to create awareness and educate staff on cybersecurity risks and trends. Employees and workers who refuse to keep up should be dismissed, and cyber awareness training programs should become necessary to stay safe and secure online.

In Cybersecurity, Security

With ever-growing challenges of cyber security risks, business applications are exposed to numerous attack vectors on a continuous basis. Being exposed to a vulnerability may disrupt confidentiality, integrity and availability of an application and its digital content. This emphasizes on the importance of application security.

Here are top tips about application security:

Assume That Infrastructure Is Insecure: As most cloud providers are opaque in terms of security practices, so it is advisable for application developers to implement enough security measures in the application to suffice its security requirements, without relying on the environment. Also, at the time of development, it is often unknown where the application will be deployed or what environment will the application operate in, so it is safe to assume that the environment will be insecure and rely on in built safety features of the application.
Secure Each Application Component: It is important to analyze every component of the application to determine the security measures it would require. Some application components such as program execution resources may require intrusion detection & prevention systems, while others such as database or storage may require access controls to prevent unauthorized elements from accessing the data. In addition to securing each application component, the firewall access should be constricted once the application moves to final production so that only appropriate traffic sources can access application resources.
Automate Installation & Configuration Of Security Components: Manual installation & configuration processes are susceptible to human error and may be bypassed in case of urgency and business pressure. Automated installation & configuration of security components ensures that the recommended measures are implemented consistently.
Test The Security Measures: Do not overlook inspection and validation of implemented security measures. Make it a point to include penetration testing in security testing protocols to gain valuable feedback on security issues that need to be addressed. Organizations may seek assistance from external parties to have an impartial evaluation of the application security and identify security gaps that may not be spotted in internal environment.
Focus On Security Monitoring: Configure the security settings to generate critical alerts. It is important to attain correct configuration so that important alerts are not hidden in a blizzard of unimportant data. This requires continuous assessment & configuration updates and use of tools to send detected anomalies to target staff for timely action.

All You Need To Know About Enemybot DDOS Botnet

By centexitguy

On April 28, 2022

In Cybersecurity

Enemybot is a new botnet that is conducting DDoS (Distributed Denial of Service) assaults on several routers and websites. It is attacking various routers and websites by leveraging existing vulnerabilities in ARM, BSD, x64, x86, and other architectures. Enemybot was identified by FortiGuard labs in mid-March.

This botnet is mostly based on the source code of Gafgyt, however it has been reported to borrow various modules from Mirai’s original source code. To avoid detection, the Enemybot employs a number of obfuscation techniques and hides Command and control (C2) server on the TOR network. The Enemybot botnet spreads and assaults other IoT devices through a variety of tactics. It attempts to gain access to systems using weak or default credentials by logging into devices with a list of hardcoded username/password combinations. By running shell commands, the bot also attempts to infect misconfigured Android devices that expose the Android Debug Bridge port (5555). Enemybot has been observed infecting Seowon Intech and D-Link routers as well as abusing a previously disclosed iRZ router vulnerability.

The bot leverages a number of known and previously disclosed loopholes, which include: –

SEOWON INTECH SLC-130 and SLR-120S routers are vulnerable to CVE-2020-17456.
Earlier D-Link routers were vulnerable to CVE-2018-10823.
CVE-2022-27226 affects iRZ mobile routers.
CVE-2022-25075 to 25084 affects TOTOLINK routers, which were formerly used by the Beastmode botnet.
CVE-2021-41773/CVE-2021-42013 is a vulnerability that affects Apache HTTP servers.
CVE-2018-20062: This vulnerability affects the ThinkPHP CMS.
CVE-2017-18368 is a vulnerability that affects Zyxel P660HN routers.
CVE-2016-6277 is a vulnerability that affects NETGEAR routers.
CVE-2015-2051 is a vulnerability that affects D-Link routers.
CVE-2014-9118 is a vulnerability that affects Zhone routers.

Once one of the foregoing problems has been exploited, the bot will use the shell command LDSERVER to download a shell script from a URL that the C2 server will dynamically update. The script then downloads the real Enemybot binary, which is adapted to the target device’s architecture. If the download server goes down, the botnet managers can update the bot clients with a new URL. The bot connects to its C2 server after being placed on a device and waits for new orders.

Enemybot’s Capabilities

Enemybot connects to the C2 server and waits for orders to be executed when a device is infected. Although the majority of the instructions are connected to DDoS assaults, the virus is not just focused on them. Fortinet presents the following set of supported commands: –

ADNS: Perform a DNS amplification attack with ADNS.
ARK: Stealth survival while launching an attack on the game’s servers.
BLACKNURSE — Flood the target with ICMP packets indicating that the destination port is unreachable.
DNS – Inundate DNS servers with DNS UDP requests that have been hardcoded.
HOLD – Flood the target with TCP connections and keep them alive for a certain amount of time.
HTTP — Send a flood of HTTP requests to the destination.
JUNK — Flood the destination with non-zero-byte UDP packets at random intervals.
OVH – Send custom UDP packets to OVH servers.
STD — Send a flood of random-byte UDP packets to the destination.
TCP — Send a flood of TCP packets to the target with forged source headers.
TLS — Carry out an SSL/TLS attack.
UDP — Send UDP packets with forged source headers to the destination.
OVERTCP — Use randomized packet delivery intervals to launch a TCP assault.
STOP — Put an end to continuous DoS assaults.
LDSERVER – Update the exploit payload download server.
SCANNER — SSH/Telnet brute-force attacks and vulnerabilities spread to additional devices.
TCPOFF/TCPON — Turn the sniffer off or on at ports 80, 21, 25, 666, 1337, and 8080, potentially to gather credentials.

Preventing Botnet Attacks

Always apply the latest available software and firmware updates for your product to prevent Enemybot or any other botnet from infecting your devices and recruiting them to malicious DDoS botnets.

One of the most common signs that your router may be infected with a botnet malware infection is that the router may become non-responsive, internet speeds drop, and the router becomes hotter than usual. In such a scenario, you should restart the router and change the passwords. It is also advised to take services of specialized cyber-security professionals to find and weed out the problem.
