Information security mainly includes the following five aspects, namely parasitism Confidentiality, authenticity, integrity, unauthorized copying and security of the system.
Information system security includes:
(1) Physical security. Physical security mainly includes environmental security, equipment security and media security. Effective technical precautions should be taken in system central rooms that handle confidential information. Critical systems should also be staffed with security personnel for area protection.
(2) Safe operation. Operational security mainly includes backup and recovery, virus detection and elimination, and electromagnetic compatibility. The main equipment, software, data, power supply, etc. of the confidential system should be backed up and the system can be restored within a short period of time. Anti-virus and anti-virus software approved by the relevant national competent authorities should be used for timely detection and disinfection, including viruses and anti-virus software on servers and clients.
(3) Information security. Ensuring the confidentiality, integrity, availability and non-repudiation of information are core tasks of information security.
(4) Security and confidentiality management. The security and confidentiality management of classified computer information systems includes three aspects: management organization, management system and management technology at all levels. Establish a complete security management organization, establish security management personnel, establish a strict security and confidentiality management system, and use advanced security and confidentiality management technology to manage the entire confidential computer information system.
Information security itself covers a wide range, including how to prevent the leakage of commercial enterprise secrets, prevent young people from browsing inappropriate information, and leak personal information.
The information security system in the network environment is the key to ensuring information security, including computer security operating systems, various security protocols, security mechanisms (digital signatures, message authentication, data encryption, etc.), until security systems, such as Security vulnerabilities such as UniNAC, DLP, etc. may threaten global security.
Information security means that information systems (including hardware, software, data, personnel, physical environment and its infrastructure) are protected from being destroyed, altered, leaked, and the system is not for accidental or malicious reasons. Can operate continuously and reliably. Information services will not be interrupted, ultimately achieving business continuity.
Information security rules can be divided into two levels: narrow security and general security. Narrow security is based on the field of computer security based on encryption. Early Chinese information security majors usually used this as the benchmark, supplemented by computer technology and communication network technology. Content related to programming; Information security in the broad sense is a comprehensive discipline, from traditional computer security to information security. Not only the name change is an extension of the development of security, security is not a purely technical issue, but a combination of management, technology and legal issues. Combine.
This major cultivates senior information security professionals who can be engaged in computers, communications, e-commerce, e-government and e-finance.
Information security mainly involves three aspects: the security of information transmission, the security of information storage and the audit of the information content transmitted over the network. Authentication Authentication is the process of verifying a subject in a network. There are generally three ways to verify a subject's identity. One is the secret known by the subject, such as passwords and keys; the second is the items carried by the subject, such as smart cards and token cards; the third is the unique functions or abilities that are only subject, such as fingerprints, voices, retinas or signatures. wait.
