Configuring Authentication. See also Guidelines for Securing Passwords for advice on securing passwords. If you want to configure Oracle XML DB to authenticate users by encrypting their passwords but you do not need to encrypt other data for example, an Intranet email, see Oracle XML DB Developers Guide for more information.

Harden Windows 10 A Security Guide gives detailed instructions on how to secure Windows 10 machines and prevent it from being compromised. We will harden the system. Oracle Database provides a set of built in password protections designed to protect your users passwords. These password protections are as follows Password encryption. Oracle Database automatically and transparently encrypts passwords during network client to server and server to server connections, using Advanced Encryption Standard AES before sending them across the network. Password complexity checking. In a default installation, Oracle Database checks that new or changed passwords are sufficiently complex to prevent intruders who try to break into the system by guessing passwords. You can further customize the complexity of your users passwords. See Enforcing Password Complexity Verification for more information. Disabling Enhanced Internet Security In Windows 2012 Server Certificate' title='Disabling Enhanced Internet Security In Windows 2012 Server Certificate' />Release Notes for Cisco AnyConnect Secure Mobility Client, Release 4. Wireless security is the prevention of unauthorized access or damage to computers using wireless networks. The most common types of wireless security are Wired. Preventing passwords from being broken. If a user tries to log in to Oracle Database multiple times using an incorrect password, Oracle Database delays each login. This protection applies for attempts made from different IP addresses or multiple client connections. Afterwards, it gradually increases the time before the user can try another password, up to a maximum of about 1. If the user enters the correct password, he or she is able to log in successfully without any delay. This feature significantly decreases the number of passwords that an intruder would be able to try within a fixed time period when attempting to log in. The failed logon delay slows down each failed logon attempt, increasing the overall time that is required to perform a password guessing attack, because such attacks usually require a very large number of failed logon attempts. The OfficeScan server and agent can be installed on endpoints running Microsoft Windows platforms. The OfficeScan agent is also compatible with various thirdparty. Nessus Plugins Windows.

Microsoft No Longer Supporting SHA1A secure gateway with a SHA1 certificate or a certificate with SHA1 intermediate. For informational purposes, what are you hosting that requires TLS From the message I suspect no server certificate exists, or the wrong EKU was used for. Enforced case sensitivity for passwords. Passwords are case sensitive. For example, the password h. PP5. 62. 0qr fails if it is entered as hpp. QR or h. Pp. 56. 20. Qr. In previous releases, passwords were not case sensitive. See Enabling or Disabling Password Case Sensitivity for information about how case sensitivity works, and how it affects password files and database links. Passwords hashed using the Secure Hash Algorithm SHA cryptographic hash function SHA 1. Oracle Database uses the SHA 1 verifier is to authenticate the user password and establish the session of the user. In addition, it enforces case sensitivity and restricts passwords to 1. The advantage of using the SHA 1 verifier is that it is commonly used by Oracle Database customers and provides much better security without forcing a network upgrade. It also adheres to compliance regulations that mandate the use of strong passwords being protected by a suitably strong password hashing algorithm. See Ensuring Against Password Security Threats by Using the SHA 1 Hashing Algorithm for more information. Minimum Requirements for Passwords. Passwords must not exceed 3. For greater security, however, follow the additional guidelines described in Guidelines for Securing Passwords. To create passwords for users, you can use the CREATE USER or ALTER USER SQL statements. SQL statements that accept the IDENTIFIED BY clause also enable you to create passwords. Example 3 1 shows several SQL statements that create passwords with the IDENTIFIED BY clause. Example 3 1 Password Creation SQL Statements. CREATE USER psmith IDENTIFIED BY password. GRANT CREATE SESSION TO psmith IDENTIFIED BY password. ALTER USER psmith IDENTIFIED BY password. CREATE DATABASE LINK AUTHENTICATED BY psmith IDENTIFIED BY password. Using a Password Management Policy. This section contains About Managing Passwords. Database security systems that depend on passwords require that passwords be kept secret at all times. Because passwords are vulnerable to theft and misuse, Oracle Database uses a password management policy. Database administrators and security officers control this policy through user profiles, enabling greater control of database security. Use the CREATE PROFILE statement to create a user profile. The profile is assigned to a user with the CREATE USER or ALTER USER statement. Details of creating and altering database users are not discussed in this section. This section describes the password parameters that can be specified using the. CREATE PROFILE or ALTER PROFILE statement. Finding User Accounts That Have Default Passwords. When you create a database in Oracle Database 1. Release 1 1. 1. 1, most of its default accounts are locked with the passwords expired. If you have upgraded from an earlier release of Oracle Database, you may have user accounts that have default passwords. These are default accounts that are created when you create a database, such as the HR, OE, and SCOTT accounts. For greater security, change the passwords for these accounts. Using a default password that is commonly known can make your database vulnerable to attacks by intruders. To find both locked and unlocked accounts that use default passwords, log onto SQLPlus using the SYSDBA privilege and then query the DBAUSERSWITHDEFPWD data dictionary view. For example to find both the names of accounts that have default passwords and the status of the account. CONNECT AS SYSDBA. Enter password password. SELECT d. username, u. FROM DBAUSERSWITHDEFPWD d, DBAUSERS u. WHERE d. username u. USERNAME ACCOUNTSTATUS. SCOTT EXPIRED LOCKED. Then change the passwords for any accounts that the DBAUSERSWITHDEFPWD view lists. Oracle recommends that you do not assign these accounts passwords that they may have had in previous releases of Oracle Database. ALTER USER SCOTT ACCOUNT UNLOCK IDENTIFIED BY password. Replace password with a password that is secure. Minimum Requirements for Passwords describes the minimum requirements for passwords. Configuring Password Settings in the Default Profile. A profile is a collection of parameters that sets limits on database resources. If you assign the profile to a user, then that user cannot exceed these limits. Aix Install Preserving Old Databases. You can use profiles to configure database settings such as sessions per user, logging and tracing features, and so on. Profiles can also control user passwords. To find information about the current password settings in the profile, you can query the DBAPROFILES data dictionary view. Table 3 1 lists the password specific parameter settings in the default profile. Table 3 1 Password Specific Settings in the Default Profile. For greater security, use the default settings described in Table 3 1, based on your needs. You can create or modify the password settings in the profile by using one of the following methods Database Configuration Assistant DBCA. When you create a new database or modify an existing database, you can use the Security Settings window to enable or disable its default security settings. The password specific settings in Table 3 1 are part of these default settings. The default security settings also include the auditing settings described in Using Default Auditing for Security Relevant SQL Statements and Privileges. Oracle recommends that you enable the default security settings. CREATE PROFILE or ALTER PROFILE statement. You can create or modify the password specific parameters individually by using the CREATE PROFILE or ALTER PROFILE statement. For example. ALTER PROFILE prof LIMIT. FAILEDLOGINATTEMPTS 9. PASSWORDLOCKTIME 1. See Oracle Database SQL Language Reference for more information about CREATE PROFILE, ALTER PROFILE, and the password related parameters described in this section. Automatically Locking a User Account After a Failed Login. Oracle Database can lock a users account after a specified number of consecutive failed log in attempts. SQL Server Central.

Every new release of SQL Server comes with new features that cause a ripple of excitement within the industry well, amongst the marketing people anyway. What happens to all the exciting TLAs that are bandied about when a new version launches Its mixed, it seems. Adam Machanics classic post, The SQL Hall of Shame, has inspired Rob Sheldon to look back at some of the features that, though worthy, have may have failed to hit the mainstream.
