Data Succession Security Issues? How to follow up on protection?

Hurry up to see if there is a data breach in the enterprise, Tencent T-SEC Security Operation Center is your intimate housekeeper, and the risk is also measurable, and relatively safe measures are taken to ensure the security of enterprise data. Hope mine solves your problem.

Lenovo PC Manager is really good, I think Lenovo PC Manager is good, and then it is also very powerful in cleaning and optimization, the most important thing is ad-free one-click scanning, fast and comprehensive diagnosis of system security status and health one-click scanning, fast and comprehensive diagnosis of system security status and health, I think Lenovo PC Manager is good.

The data anti-leakage and re-encryption software is divided into free stand-alone shared encryption software and the network version of enterprise-level anti-leakage software, and the enterprise-level anti-leakage software is divided into anti-leakage software with driver layer encryption algorithm and anti-leakage software with application-layer encryption algorithm. The data security of Haiyu security software includes functions such as transparent encryption and decryption of files, internal file circulation, confidentiality control, offline management, file outgoing management, flexible approval process, working mode switching, server whitelist, etc., to fundamentally prevent information leakage and ensure information security.

The security protection construction of IDC data room can be carried out from the following aspects:

Network security: Establish a complete network security protection system, including firewalls, intrusion detection systems (IDS), network audit systems, vulnerability scanning systems, etc., to protect the computer room from network attacks and illegal access.

Physical security: Strict control is placed on who enters and exits the data center to ensure that only authorized personnel can access the data center. At the same time, the computer room should be equipped with surveillance cameras and access control systems to monitor the inside of the computer room in real time and record all personnel and time entering and leaving the computer room.

Host security: Strengthen the security of the host, including disabling unnecessary services, restricting login permissions, and installing antivirus software. At the same time, patches and security hardening software should be updated regularly to improve the security of the host.

Application security: Strengthen the security of the application system, including access control, data encryption, and identity authentication of the application system. At the same time, security audits and vulnerability scans should be conducted on application systems on a regular basis to discover and fix potential security issues.

Data security: Encrypt and back up data to prevent data leakage and corruption. At the same time, a sound data management system should be formulated to ensure the confidentiality and integrity of data.

Emergency response: Formulate a comprehensive emergency plan, including emergency response process, backup and recovery strategy, etc., to ensure timely response and system recovery in the event of a security incident.

Safety training: Conduct regular safety training for employees to improve their safety awareness and skill level to reduce the impact of human factors on system security.

In short, the security protection construction of IDC data room needs to start from multiple aspects and establish a complete protection system to ensure the security, reliability and stability of the system.

Before construction, it is necessary to determine the location. The location of the data center is one of the key decisions for the construction of the data center. Security is extremely important for data centers, so when selecting a location, it is necessary to consider the probability and frequency of natural disasters (floods, hurricanes, tornadoes, etc.), environmental hazards, climate factors, etc., to minimize the risk factors.

Secondly, consider factors such as the power source**, communication infrastructure, transportation and other factors of the alternative location. Second, consider what level of data center to build. The world-recognized data center standards organization and the third-party certification body Uptime Institute divide data centers into four levels: Tier I to Tier IV, with higher levels and stronger security.

The tier level of a data center determines the redundancy requirements of the data center, power distribution paths, and more. Once you've determined the level of your data center, you can decide what redundancy design you need. Third, the number of racks determines the space requirements of the data center.

To determine how many racks you need and how big they are. Estimate the space you need in your data center by the size of the racks and the number of racks. In addition, power supply, HVAC, network bandwidth, environmental monitoring, and security operation and maintenance are all key issues that need to be considered, so I will not talk about them one by one.

All in all, the construction of the data center computer room has a high approval level, a long construction period, high technical difficulty, and high construction cost, which is a huge project, if it is a large enterprise or a company with very high requirements for data security, such as banks, financial companies, etc., you can build your own computer room to manage and maintain the server, if it is an ordinary enterprise, it is more economical to choose server hosting.

With the development of the Internet, people can use IDC to do cloud computing and big data analysis, as well as CDN acceleration.

To build an IDC, the first thing is to have a stable environment (safety, large space, strong seismic level of the computer room), dust-free, and special personnel to supervise and maintain; The access capacity of the computer room should be strong, and the access bandwidth should reach 1G or even 10G. The cabinet is equipped with 2U and 4U, equipped with alternating current and direct current, and the computer room should be able to withstand the support of electricity; IDC computer room facilities include electrical, power supply, air conditioning, fire protection, security monitoring, lightning protection, transmission these specialties, the construction needs to consider the seismic level of the building, the most basic is to pass the certificate issued by the Ministry of Industry and Information Technology, that is, the license, in order to establish the IDC computer room; The IDC construction project is huge, the cabinet power transmission is done well, and the network must be built, and then the installation system such as the equipment server is installed, and then the business is gradually improved.

The existing problems of cloud computing applications are mainly as follows:

1.Virtualization security issues: If a physical host is compromised, the virtual server it manages may be overcome due to the existence of communication with the physical host, and if the physical host and the virtual machine do not communicate, the virtual machine may escape.

If the virtual network on a physical host is compromised, the virtual machine will also be compromised due to the presence of a scenario where the physical host communicates with the virtual machine and one virtual machine monitors the other.

2.Security issues in data centralization: User data storage, processing, and network transmission are all related to cloud computing systems, including how to effectively store data to avoid data loss or corruption, how to isolate data for multi-tenant applications, and how to avoid data service blockage.

3.Cloud platform availability issues: Users' data and business applications are in a problematic system where the cloud platform is under attack, and their business processes will rely on cloud platform service continuity, SLA and IT processes, security policies, event processing, and analysis, which pose challenges.

In addition, when a system failure occurs, how to ensure the rapid recovery of user data has also become an important issue.

4.The problem of cloud platform attacks: Cloud computing platforms are easy to become the target of hacker attacks due to the high concentration of users and information resources, and the consequences and damage caused by denial of service will be significantly greater than that of traditional enterprise network application environments.

5.Legal risks: cloud computing applications are weak in geography, information liquidity is large, information services or user data may be distributed in different regions or even different countries, and there are legal differences and disputes in information security supervision; At the same time, the problem of forensics that may be caused by the blurring of physical boundaries between users caused by virtualization and other technologies cannot be ignored.

There are three aspects to the security of cloud computing:

1) The cloud computing platform gathers a large number of users and data resources, which is easy to attract attacks, and once a failure occurs, its impact scope is more numerous and the consequences are more serious. In addition, its openness also puts forward higher requirements for the security of the interface. In addition, multiple tenants are integrated on the cloud computing platform, and how to securely isolate information resources between multiple tenants has also become a prominent issue in cloud computing security.

2) The new service model of cloud computing separates the ownership, management and use of resources, so users lose direct control over physical resources and will face some security problems in collaboration with service providers, such as whether users will face obstacles to service withdrawal, and incomplete and insecure data deletion will cause damage to users, so how to define the different responsibilities of users and service providers is also an important issue.

3) The traditional protection mechanism based on physical security edges is difficult to effectively protect user applications and information security in a shared virtualization environment.

Cloud computing security.

1. Infrastructure security.

Infrastructure security includes server system security, network management system security, domain name system security, network routing system security, LAN and VLAN configuration, etc.

2. Data security.

Meeting the requirements of cloud data security requires the application of existing security technologies and the adherence to sound security practices, and the various safeguards must be considered holistically so that they constitute a resilient barrier.

3. Identity authentication and access management.

4. Application security.

5. Virtualization security.

Virtualized security is two-fold:

The first is the security of the virtual technology itself.

The second is the new security problems introduced by virtualization.

1. The system security of virtual machines brought about by virtualization.

Virtualization technology plays a major role in system organization, reducing system operating costs, and improving the efficiency, utilization, and flexibility of hardware resources. However, virtualization technology itself not only faces the existing security threats of traditional networks, but also faces the security problems introduced by itself.

If a system is infected with a virus, whether other systems will be affected, whether the isolation work can be done well, and even whether the storage and data information in the background will be affected. If a virtual machine crashes, it is a real question of whether it will affect other virtual machines.

2. The rise of e-commerce brings about identity authentication security, personal information security and transaction security.

E-commerce has become an important development direction of the Internet, at present, the annual national network has accounted for 9% of the total transaction volume of the year, and many valuable and large items also have a trend of trading on the network.

Therefore, the security of e-commerce transactions has become a very urgent problem, and in this regard, the security protection of users is very weak, personal transaction password theft, or bank database information leakage problems emerge in an endless stream, becoming a new security hotspot.

3. How cloud computing can ensure the security of its own key business data.

Enterprises put their own business in the cloud data center, how can users in the system easily share, saving a lot of things. It looks beautiful, but what about security issues, what if the data is leaked?

This is a question that every CIO is beating in his heart, this problem is not only a security issue, but also an informatization planning problem, and it is necessary to be familiar with all aspects of cloud computing, which layer to use as virtual and how to do it. These questions present both opportunities and challenges for security vendors.

4. Security problems caused by the impact of mobile users on traditional networks.

With the popularization of smart phones and the development of mobile Internet, the security of mobile terminals is challenging the traditional network attack and defense system. As we all know, the traditional security protection in the past was to guard the ports of our servers, and use firewalls, anti-viruswall, and traffic monitoring to form a Maginot line of defense, so that mail servers, database servers, and all kinds of attacks from the outside will be kept out.

However, when the mobile Internet is integrated into the conventional network, it is estimated that the previous plane has become three-dimensional. Many email viruses or attacks are introduced from mobile phones or PDAs, which makes conventional protection systems extremely challenging.

Enterprises that want to ensure cloud data security need to recruit the right talent, which has given rise to a new high-paying industry - cloud security engineers.

1. Eye and face protection.

1) Full protective glasses (Eyes and face are the most vulnerable parts of the laboratory to accidents, so their protection is particularly important.) In the laboratory, experimenters must wear safety protective glasses.

2) When chemicals get into your eyes, rinse them thoroughly with water immediately. To rinse, the eyelids should be spread open, carefully rinsed with tap water for a few minutes, then rinsed with distilled water, and then taken to the infirmary**.

3) Face protection is used to protect the face and throat. In order to prevent possible ** and harmful gases from the experiment, a plexiglass protective mask or respiratory protective equipment can be worn.

2. Hand protection.

1) In order to prevent hand injury in the laboratory, you can choose to wear a variety of gloves as needed. Gloves must be worn when in contact with corrosive substances, objects with sharp edges (e.g. broken glass, wood, metal shards), and substances that are too hot or too cold.

2) Gloves must be used with care to ensure that they are not damaged.

3. Body protection.

1) Staff are not allowed to wear sandals and slippers, and chemical workers are strictly prohibited from wearing high heels to enter the laboratory. Flat-soled, non-slip, synthetic leather or leather shoes should be worn.

2) All personnel must wear work clothes when entering the laboratory, the purpose of which is to prevent the body and clothing from being contaminated by chemicals.

3) Workwear is generally not resistant to chemical corrosion, so when it is severely corroded, these workwear must be replaced and renewed.

4) In order to prevent the spread of chemicals attached to work clothes, work clothes should not be worn in other public places such as canteens, conference rooms, etc.

5) Wash your work clothes once a week.
