Chapter 6 security defense practices for iOS apps: files that cannot be destroyed Think of a common file system as a big notebook. When a file is deleted, many people think that this page is completely hacked with the trigger, just like the confidential document about Area 51. But in fact, what happened behind this operation is more like drawing a huge X on this page with a very small red pen. The file is marked as deleted, but the content still exist

Therefore, internal message communication is very important, and the number of messages sent and replied should be considerable, especially for large enterprises, therefore, you can use the enterprise ID to communicate Internal messages. Enterprise numbers are suitable for internal enterprise

Unlike automatic database backup, the system administrator must take certain actions to protect data from unauthorized users. If you are using MySQL, you can use some convenient functions to protect the system and greatly reduce the risk of unauthorized access to confidential data.

application does not need to be modified because the newly created view is defined as the user's original relationship, keep the user's external mode unchanged, and the user's application can still search for data through the view.Of course, a view can only provide logical independence of data to a certain extent. for example, a view update is conditional, therefore, the statement for modifying data in the application may still change due to the change in the basic table structure.4.

More and more enterprises have listened to the opinions of regulatory agencies and increased the intensity of database encryption to ensure the security of data information in the event of large-scale violations. However, without a strong and effective key management practice specification, these enterprises may find that their data encryption measures are just useless. "Encryption key management is the most important part," said Pravin kotali, CEO of CipherCloud. If you cannot handle keys, it i

Open "start"-"run", Enter CMD, and press Enter. In the "command prompt" window, first confirm the disk partition where the encrypted folder is to be created, and then enter: md disk partition: the name of the encrypted folder to be created... For example, if the disk partition of the encrypted folder I selected is "F" and the encrypted folder name is "q ". Then, enter md f: q... in the command prompt, and a folder named "q" will be created in drive f. We can't open it, but we can't delete it. H

Its main functions include the following: · Data definition functionDBMS provides a data description language (DDL) through which you can define data. ·Data manipulationDBMS also provides a data control language (DML) for basic database operations: Query, insert, delete, and modify. ·Database Operation ManagementThis is the core part o

managing the application blacklist or whitelist does not cover all applications. In this case, the Organization's Intranet security level depends largely on the user's IT security awareness level, this is obviously a token. The existence of sandbox technology provides new ideas for solving application compliance. Using sandbox technology, IT administrators can automatically put untrusted or non-whitelist programs into the sandbox for operation, even if a program with potential risks is download

Researchers claim that a new hacker technology named "BREACH" is hot-hitting to extract login tokens, session IDs, and other sensitive information from SSL/TLS encrypted network traffic. Confidential data has now become an important basis for online banking and online shopping systems, but the emergence of new technologies can interpret the specific content within 30 seconds. BREACH attacks common Deflate data compression algorithms. This algorithm is

Security testing is a process in which confidential data is kept confidential and users can only perform operations within the authorized scope. For example:A confidential content is not exposed to unauthorized individuals or user entitiesUser B cannot unilaterally block a function of the website. What are the security testing aspects? SQL Injection (SQL Injectio

, such as disguising them as other operating systems, so that attackers will think they are attacking a Windows NT or Solaris system. Encrypted File System Encryption technology plays an increasingly important role in the security of modern computer systems. The encrypted file system introduces the encryption service to the file system to improve the security of the computer system. There are too many reasons to encrypt the file system, such as preventing Hard Disk theft and unauthorized access

, but due to poverty and lack of experience in programming practices. This is a fatal and simple attack that executes from a remote location. In SQL injection, we use various commands of the database server and obtain various data from it. In this guide, I will discuss three aspects of SQL injection, namely bypassing logon, accessing confidential data and modifying webpage content. Therefore, let our heads really roam .. Bypass Logon Assume that only

Why does the website require https to prevent hacker attacks? Everyone knows a famous online saying and famous cartoon "on the Internet, no one knows that you are a dog ": This is dangerous for online shopping and e-commerce, because you cannot and shouldn't trust the company called XX (XX brand) in your mind, the real-world company XX (XX brand). At the same time, the IP technology used by the Internet is to transmit all information in plain text. In this way, this makes it possible for any

SSL is located under the Application Protocol (such as HTTP), and SMTP is located above the connection protocol TCP/IP. Microsoft internet Information Server supports Hypertext Transfer Protocol (HTTPS) access. Although SSL can provide the a

Recently, a Romanian hacker nicknamed "Unu" disclosed on his blog that he found an SQL injection vulnerability on the British Parliament's official website, which exposes a lot of confidential information, including unencrypted logon certificates. Using this vulnerability, he claims that as long as a database command is added to the webpage address in the browser, the related confidential data can be stolen
