Some important measures to maintain corporate information security

[haoqiniao]

While all companies are struggling in times of economic crisis, cybercriminals are snickering in the dark. Sensitive data, company customers, and company infrastructure all face huge security risks. Possible problems include data leaks, malicious websites, malicious sabotage by disgruntled employees, and uncontrolled partners.

However, there are still ways to strengthen enterprise security (for example, do not use those third-party servers. All employees of the company can communicate with each other as long as they register an account on their server. All messages and files sent and received are very likely to be transferred through third-party servers, which will inevitably cause great hidden dangers to enterprise information security.) Choosing quick-effective strategies can help enterprises control various security threats without neglecting network infrastructure security. The 10 tips provided in this article are strategies to protect enterprise information security. They can help enterprises improve risk management and control without investing in high funds and human resources, and achieve the purpose of improving security in the shortest time.

1. Protect the security of the main switch

First of all, we can lock those unused network ports and save money by controlling the overall power consumption through switches (such as Adtran and D-link, turning off the power when no power is needed). The investment in this equipment can see results within one year.

Automatic shutdown can better protect the security of unused ports by preventing prying computers from entering sensitive parts of the network, while automatic shutdown can also improve physical security, especially in buildings that are open to public access (such as hospitals and government offices).

2. Double-check low-cost endpoint security

There are many endpoint security appliances and agents that are expensive and require lengthy lead times to deploy.

If you don't want to spend so much money, then the best solution is to buy a laptop with TPM function and start using some form of protection, such as fingerprint recognition or encryption keys (stored on the TPM to prevent unauthorized users from operating the system). Combining TPM and identification technology can effectively protect system security, and only verified personnel can operate the system.

3. Get a VPN for free

If you haven't deployed a VPN yet, now is the time. As company employees become more mobile, sensitive data stored in WiFi hotspots or hotel employee laptops can easily be stolen. Moreover, a VPN can also come in handy when you want to securely extend network sharing over the Internet or access system files outside the company.

Of course, you can spend tens of thousands of dollars to deploy VPN technology, but if you just need some basic simple protection, you can also choose VPN software that is cheap or even free, as long as you have a broadband connection. Free open source VPN products are available on the OpenVPN.org website. LogMeln's Hamachi is another free software that individual users can choose, and the installation process is very simple. FileShareFreak also provides some other similar products.

The trick is to popularize the use of these VPN products within the company and provide support resources for first-time VPN users. Free VPN products can also be used as a "touchstone" for more advanced VPNs to decide whether to purchase a more professional VPN in the future.

4. Avoid unnecessary Cisco fees

In the new year, it's time to go back and take a closer look at the product support fees provided by Cisco. These fees are mainly used to maintain the current IOS version and maintenance related time. You should consider whether you should purchase a replacement device as a backup or explore another provider that won't charge additional fees for firmware and router operating system software upgrades (Adtran is one such software). Doing so can see results in the short term and save the company a lot of expenses.

5. Deploy encryption system

Since then, encryption technology has been considered a "good, but expensive and difficult to implement technology." However, in recent years, many free or cheap email and disk encryption tools have appeared, so this is the year that enterprises should start to actually implement encryption of removable disks and emails.

Two great options are available here: the free open source software True Crypt and Voltage Security's low-cost but easy-to-deploy Voltage Security Networ service.

TrueCrypt's disk encryption client can encrypt Mac, Linux and Windows systems. Although the encryption software lacks enterprise-level management tools, it is a good choice for small enterprises, managers and work groups. Email encryption provided by Voltage does not require any client installation and can be used with Outlook and Webmail. Priced at $65 per year per year, Voltage handles all management details and the hosting service can be implemented easily and quickly.

Others are PGP's encryption products, which cost less than $100 per unit, depending on the quantity selected by the user. All deployment of these products makes encryption key management very simple: the disadvantage of deploying enterprise-level encryption is that it is difficult to solve the problem of expired keys when employees leave or the problem of recovering keys when employees forget the keys. It is also impossible to control the problem of employees leaving the enterprise and taking data away. It can prevent others, but it cannot protect itself, and it cannot prevent employees from copying their own data.

Nowadays, more and more enterprises adopt enterprise transparent encryption systems to solve the shortcomings of disk encryption. Companies have also changed from passive to active. Udun Intelligent Information Leakage Prevention System adopts underlying driver transparent encryption and decryption technology. Without changing the original workflow and file usage habits of the enterprise, it implements monitoring and mandatory encryption protection of key data files within the enterprise, effectively preventing passive and active leaks. Protect corporate documents.

6. Understand the IDS system

You may think that setting up a rough intrusion detection system is enough, but now is the time to take a closer look at your IDS and adjust the IDS to your company's specific circumstances. This means adjusting the configuration of the IDS, understanding its reporting and login behavior, and doing some initial analysis.

Of course, this will not bring obvious consequences, but with so many security risks now, we must spend more time conducting IDS analysis to understand the intrusion detection situation. If you are using Snort as your main IDS, please visit Richard Bejtlich's podcast and the snort.org forum for more information.

Another option is to train one or two of the company's employees to understand the system's features and ways to enhance system security. Although the cost of training is the first expense to be ignored during an economic crisis, it is also a way to provide a quick return on investment, and a small amount of money can provide additional security protection for the system.

7. Really ban ex-employees from accessing systems

What we are discussing here is all employees who were laid off in the wave of layoffs, not just the IT department. From a company perspective, the biggest threat today comes from employees who were once part of the company and are now unemployed. Research shows that ex-employees can become a company's security nightmare. Never changed the password of any key server? Multiple machines using the same host password? Well, it's better to change these bad habits now.

Other risks posed by the former employee should also be assessed. Are the company's access policies up to date? Have all the former employee's security keys, passwords, and access codes been disabled? Are the former employees still able to use the remote gateway? Now is the time to check access logs to ensure that the departing employee's access directory entries have been deleted.

8. Get rid of SQL injection attacks

SQL injection basically refers to entering the system database through an unprotected backdoor. Hackers can create and execute backdoor programs without any programming knowledge and little ability. This is also the reason why SQL causes headaches.

Truly eliminating SQL injection counterattacks requires the cooperation of several different parties, working together to ensure that no security holes are missed. Another reason is that vulnerable websites are easily found by Hackers. Hackers only need to enter a few keywords on Google to find the website title, and there is no need to even search your network.

Now, let’s try to solve this problem and carefully check all applications to ensure that your website never appears on the Hacker list again. First, conduct an audit, hire a professional consulting firm or learn how to fix database/web server programming. Visit OWASP.org for more information on accurately setting up database access and how to check for vulnerabilities.

In addition, you can also download Acunetix's free Web Vulnerability Scanner and various free HP evaluation tools, or you can try modsecurity.org's open source Web App Firewall software.

Of course, if these free scanning programs do not find any vulnerabilities or problems, it does not mean that your system is 100% safe, but at least you can understand how the boss will use these tools and understand the vulnerabilities of the system. The method is to regularly scan the system to ensure that no hacker can create any malicious programs.

9. Prevent data leakage

A single data breach lawsuit can ruin an entire company's reputation, and as more and more data begins to spread across the Internet, it's important to look at low-cost tools that can prevent data breaches or proactively defend against them. Code Green Networks and eTelemetry Metron SE are two representative products. They are easy to deploy and very cheap, and they can also expand related functions.

Udun's intelligent information leakage prevention system adopts transparent encryption and decryption technology to monitor and enforce encryption of key data files within the enterprise without changing the company's original workflow and file operation habits, effectively preventing passive and active leaks.

10. Use enterprise IM software with its own server

Do not use corporate IM that provides servers provided by third parties. All employees of the company can communicate with each other as long as they register an account on their servers. All messages and files sent and received are very likely to be transferred through third-party servers, which will inevitably cause great hidden dangers to corporate information security.
