information systems monitoring certification, said: " Isaca is aware of the need to provide a differentiated network security training and certification approach, as global businesses need more effective ways to discover and hire skilled professionals. In today's threatening environment, technicians who rely on unskilled training and certification are like those who rely on a military strategy guide but ha

amount of storage space, you can store the user's private key and digital certificates, the use of USB key built-in public key algorithm to achieve user identity authentication. Because the user's private key is stored in the password lock, it can not be read theoretically in any way, so the

. At the same time, the firewall cannot protect attacks from internal networks and viruses. Therefore, the firewall protects the network passively. The attacked network does not know who initiated the attack on the network, and what method has been taken to achieve the attack purpose, I don't even know what measures should be taken to protect the

(mostly malicious. Therefore, you must ensure that all ports are regularly reviewed and all unused ports are blocked. Regularly review network entry pointsYour network may constantly change the size and increase the entry point. Therefore, you can regularly check all the ways to access the network in your organization. Be careful with all the entry points. You s

are available: Wired Equivalent privacy protocol (WEP) and Wi-Fi access protection protocol (WPA ). In fact, only one of the protocols can be used at a time. Regular changes to keys may also help protect the network. With any license, you should first choose to use WPA, because WEP may be decrypted by hackers using special software. Strengthen key management Even if the encryption algorithm is used, if the

At present, with the increasing of the network degree of pharmaceutical industry, the informatization construction of drug production enterprises is also in full swing. Nowadays, the information security problems faced by enterprises are becoming more and more complex, and all kinds of threats of network security are i

Cryptojs (Crypto.js) provides a variety of cryptographic algorithms for JavaScript.Des symmetric encryptionIn symmetric encryption algorithm, the sender of the data sends the plaintext and the encryption key together after the special encryption algorithm processing, causes it to become the complex cipher cipher to send out. After receiving the ciphertext, if you want to interpret the original text, it is necessary to decrypt the ciphertext by using t

Authentication-password control We recommend using password control on wireless network sites-of course, it is not necessary to be confined to wireless networks. Network operating systems and servers such as Novell NetWare and Microsoft NT provide built-in multi-level security services, including password management. The password should be under strict control a

, therefore, you need more security settings. The next step to reinforce the Wireless Home Network is to enable encryption. By default, the encryption function is disabled on the wireless devices that leave the factory. To enable the encryption function, we must set a security key that is only available to the wireless

Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. 4.

You should consider how to fully protect the security of all channels, prevent illegal files and applications from entering, and prevent undetected or sensitive information from being leaked. Consider placing

devices such as R2 need to use the R1 public key to encrypt data, R2 must make sure that this public key must belong to R1, instead of a public key belonging to a "villain", the most scientific way for R2 to determine whether the public key belongs to R1 is to check whether the public

your Local Security Policy settings through the Window Control Panel or by running secpol. msc or secpol. msc. Remember, the key settings you need to do include: to enable audit failure events, you must use Ctrl + Alt + Del to log on, create a password policy, and enable text messages for users who attempt to log on, when a user logs on, he/she informs the user of acceptable usage policies and does not dis

legitimate application of SQL statements all captured, unified into the "white list", to prevent legitimate statements are false, through the semester perfect period, and then switch to the protection period, At this point, if there is a bulk export of sensitive data through the Web Access application backdoor, the database firewall will report "new statement", such statements belong to the "gray list" statement, the security administrator to judge t

When the customer's computer wants to obtain the desired list of network resources, it first broadcasts a browser request. After the browser master server receives the request, if the requested list is the browsing list of this group, directly send back

. The default wireless LAN has absolutely no security at all, and almost all APS are configured to turn on WEP for encryption or use the default key provided by the original manufacturer. Because of the open access mode of WLAN, the hacker can enter the wireless network through its default password. Once the wireless LAN is connected to the enterprise, the hack

First, the preface My experience tells me: Information security is a kind of artificial confrontation against information protection, it is the competition between man and man in technology and thinking, and it is the war of real "no smoke". The way of attack is multi-faceted and multi-level, so it is a complicated project to establish an effective information security guarantee system, it is a "war" becau

Intruders can destroy and intrude through highly sensitive receiving devices. The default Wireless LAN has no security at all. Almost all APs enable WEP Encryption Based on the default configuration or use the default ke
