14. Local Security Policies
Local Security Policies enforce standards amongst the organization to
strengthen its security posture as a whole
Click Start -> Control Panel -> Performance and Maintenance ->
Administrative Tools -> Local Security Policy
Password policy
Defining and enforcing strong password policies for an organization can help
prevent attackers from impersonating users and help prevent the loss,
exposure, or corruption of sensitive information
Account lockout policy
Disables a user account if an incorrect password is entered a specified
number of times over a specified period
Audit policies
Monitoring the creation or modification of objects gives a way to track
potential security problems, helps to ensure user accountability, and provides
evidence in the event of a security breach
15. Local Security Policies
Define a strong password policy
Enforce password history – set to “5”. A user cannot use the same
password when their password expires.
Maximum password age - default is "42". This specifies how long a user
can use the same password. After 42 days, the user must change his/her
password. Set to “90” for user accounts and “30” for administrator.
Minimum password length - set to "8". This means that a password must
be at least 8 characters long.
Password must meet complexity requirements - set to "Enabled". This
means a password must include upper and lower case letters, a number
and a special character.
Store password using reversible encryption for all users in the domain -
always leave "Disabled". If you enable this policy, all users' passwords will
be easy to crack.
16. Local Security Policies
Define an account lockout policy
These policy settings help you to prevent attackers from guessing users'
passwords, and they decrease the likelihood of successful attacks on your
network.
Account lockout duration - the number of minutes a locked-out account
remains locked out before automatically becoming unlocked
Account lockout threshold - the number of failed logon attempts that causes
a user account to be locked out
Reset account lockout counter after - the number of minutes that must
elapse before the failed logon attempt counter is reset to 0
Be careful not to set these too low. If users lock themselves out because
of mistyping their passwords, this can provide for more work for your
organization.
17. Local Security Policies

DLL activity
Name, what the process is doing (operation), the result and details
34. User Accounts
Local Users and Groups limit the ability of users and groups to
perform certain actions by assigning them rights and
permissions
User accounts
A collection of information that tells Windows what files a user can
access, what changes a user can make
Allow multiple users to share a computer, but still have their own files
and settings
Each user accesses their user account with a user name and password
Administrator account
Can change security settings, install software and hardware, and access
all files on the computer; including make changes to other user accounts
35. User and Group Account Permissions
Permissions are customizable by individual user or by a group of
users
Full Control – all file permissions granted (administrator level)
Modify – permission to change content but not ownership of files;
cannot delete files or folders
Read & Execute - permission allows or denies the user to read and
execute files
List Folder Contents - permission allows or denies the user from viewing
file names
Read - permission allows or denies the user from viewing the attributes
of a file or folder
Write - permission applies only to files and allows or denies the user from
making changes to the file and overwriting existing content by NTFS
36. User and Group Account Permissions
Inherited permissions
If an object’s permissions are shaded, the object has inherited
permissions from the parent object
Three ways to make changes to inherited permissions
Make the changes to the parent object, and then the object will inherit
these permissions
Select the opposite permission (Allow or Deny) to override the inherited
permission
Clear the Inherit from parent the permission entries that apply to child
objects
37. Account Permissions Best Practices
User accounts settings
Limit Administrative Privileges
Make sure user accounts are set to ‘limited’
Do not give ‘full control’ as that equals Administrator access
Running as Administrator may allow malicious software to gain access
Make sure all accounts have passwords
Disable Guest account
Administrator account
Change password - Administrator account has default or no password
upon initial installation
Obfuscate the account - change name
Don’t use the account
Websites have default passwords published
http://www.phenoelit-us.org/dpl/dpl.html
38. Local vs. Domain Accounts
Local account
Username and encrypted password are stored on the computer itself
Permissions apply only to this computer
Domain account
Resides on a Domain Controller
A server that manages access to a set of network resources such as print
servers, applications, etc.
A user can log into the domain controller and is given permissions to all
network resources
Username and password are stored on a domain controller rather than
on each computer the user accesses
Permissions apply to a network of computers and peripherals
Network administrators only have one place to store user information
