Securi-Pi: Uses Raspberry Pi as a stepping stone for securityGuideLike many readers of LinuxJournal, I have also lived a very common "technology nomadic" life today, from one access point to another between networks, we are in different places in the real world, but we are always connected to the Internet and other networks that are commonly used. Recently, I have found that more and more network environments are starting to block common external port

For composite indexes, if the bootstrap column of the composite index appears after the where condition, index range scan may be executed. Index fast full scan (index fast full

Use ZBar in iOS to scan the QR code to customize the scan interface, and use ioszbar to scan the interfaceZXing has been used in Android to identify QR codes. ZXing also has the corresponding iOS version. After understanding it, ZBar is also a common QR code recognition software, the sdks for iOS and Android are provided for use. Finally, I chose ZBar for QR code

Port Scan 234 Layer discovery is only to accurately discover all live host IP, identify attack surface, port scan to discover attack point, Discover open port. The port corresponds to the Network service and application program, and the vulnerability of the service-side program is hacked through the port. "All scan results, do not fully believe that" a port is a

Haha, I am in a good mood today. I am complaining about this scan problem...At present, I usually use TCP or SYN scanning. This FIN scan is not commonly used. It is also called a secret scan.The following three methods will be used for a small discussion. For more information, please advise!I. Why is TCP scanning slow? This method sends a connection request packet segment from a port on the local host to a

For clustered index scanning, we first know that the data is a tree data structure arranged by the index key as the leaf node. The data in each row in the table is attached to the index key, the fastest way to perform data search for such a table is, of course, "clustered index search ". Under what circumstances is "clustered index scanning? When the condition field of the data you want to search for has no index, the query executor will read the data in the entire table one by one to confirm th

This article is applicable to the reading references of the attacker who has some in-depth knowledge about database indexes. We are easy to understand clustering index scanning and table scanning, but it is not easy to understand non-clustered index scanning. This is often confusing for beginners, the reason is that there is no need for non-clustered index scanning, because if the query results are not highly selective, clustering index scanning can be used in clustered index tables, why does a

Index full scan and index fast full scan look similar to each other. They are both common and personalized. The commonality between the two is that scanning is not required.You can directly return all the required data through the index. This is undoubtedly one of the rare data access methods to improve query performance, because the data stored in the index is usuallyIs much smaller than the original table

In front, you Xia introduced some knowledge about database vulnerability scanning and launched an "Authorization scan" for Oracle databases. Now we perform a "weak password scan ", because weak passwords are almost the biggest threat to databases, we listed "weak password scanning" in database vulnerability scanning ". The target of this project is still the Oracle database. As mentioned in the previous art

MySQL optimizes group by (loose index scan and compact index scan) and mysqlgroup The most common method to satisfy the group by clause is to scan the entire table and create a new temporary table. All rows in each GROUP in the table should be continuous, then use the temporary table to locate the group and apply the accumulate function (if any ). In some cases,

1) Full Table scan (Full Table Scans, FTS)To scan the entire table, Oracle reads all rows in the table and checks whether each row meets the WHERE restrictions of the statement. Oracle reads each data block allocated to the table sequentially until it reads the highest waterline of the table (high water mark, HWM, marking the last data block of the table ). One multi-block read operation enables I/O to read
