Two ways to use Security Automation
User authentication is usually performed by entering a user name and password. This information is called user credentials and should only be known to the user, so that no third party can gain access to the system under a false identity. This post explains how a user's password protection can be circumvented and how to prevent it. SAP system legacy data The login data of a user, including password, are saved in the USR02 database table. However, the password is not in plain text, but encrypted as a hash value. For each user there are not only one but up to three generated password hashes. Different algorithms are used to calculate these values, but only the Salted SHA1 can be considered sufficiently safe. Table deduction USR02 The secure password hash is located in the fifth column of the pictured table deduction with the heading Password hash value. The corresponding data field in the column is called PWDSALTEDHASH. Weak Password Hash Risks You have a good and working permission concept that ensures that no processes or data can be manipulated or stolen. A potential attacker now has the ability to read out your database with the password hashes. The hash values are calculated using password crackers, which are available on the Internet at home, and the attacker now has a long list of user credentials. To damage your system, the user will now search for the appropriate permissions and perform the attack under a false identity. Identifying the actual attacker is virtually impossible. Check if your system is vulnerable too Your system generates the weak hash values if the login/password_downwards_compatibility profile parameter has an unequal value of 0.
This prevents that just because someone would start a new chain, someone would accidentally recognise it as "reality". However, sometimes two miners working on the longest chain find a new block at the same time. This is called Orphan Blocks. The chain now has in principle two end pieces (2 parallel blocks). Different miners now work at different ends of the chain. The blockchain will then continue where the next block will be found first. The other block is called the Orphan Block, and it's sort of a dead branch of the blockchain. So how do you explain the above things to your grandma?
The past ten years have primarily revolutionized the infrastructure and database layer. The fascinating thing is that there have been hardly any changes to the SAP installation program SAPinst during this time.
This opens up new possibilities for SAP administration. Basic services, for example, can also be rented from SAP or obtained from an external service provider as part of managed services.
Use "Shortcut for SAP Systems" to accomplish many tasks in the SAP basis more easily and quickly.
Use Transaction OSSordering the desired support packages in the SAPNet - R/3 frontend.
It is recommended to use only one automation tool (SAP Solution Manager or SAP LVM).
