These two indicators have a strong correlation, and I think the focus of refining black box testing, so put together.
First of all, we need to understand what to test what kind of content, that is, we need to have a principled guidance content, for example: we can choose
As the saying goes, the best defense is offense, and this sentence applies to the field of information security as well. Next, we will introduce you to the 15 latest web security sites. Whether you're a developer, security expert, auditor, or penetration tester, you can use these sites to improve your hacking skills. Practice makes perfect, please always keep this in mind!1.

code are executed. A logical class of vulnerabilities, such as the above, often requires consideration of the risk of being bypassed and attacked in a particular business scenario. Incorporating security processes into the software development lifecycle is the best way to circumvent such vulnerabilities. Security Review ensures that business logic is not bypassed, the accuracy and security of user data flow is ensured before the code implements the functionality.Figure 2 2015 Application Vulner

100 words.Solution: (1g=5000*200k, divide the file into 5,000 small files, 200k per file)1) Divide-and-conquer/hash mapping: In sequential read files, for each word X, take hash (x)%5000, and then follow that value to 5,000 small files (recorded as X0,x1,... x4999). So each file is about 200k, and each file holds a word with the same hash value. If one of the files exceeds the 1M size, you can continue to do so in a similar way until the size of the resulting small file is less than 1M.2) Hash

until the size of the resulting small file is less than 1M.2) Hash statistics: For each small file, the use of Trie tree/hash_map and other statistics in each file appear in the word and the corresponding frequency.3) Heap/merge sort: Take out the 100 words with the most frequent occurrences (you can use the smallest heap with 100 nodes) and deposit 100 words and corresponding frequencies into the file, so that you get 5,000 files.
