This document discusses data security and password protection. It explains that passwords should be strong, with a minimum of 6 characters including letters, numbers, and symbols. Longer passwords are more secure, with 12+ character passwords being very secure. The document also discusses encryption, explaining that encryption translates plain text into encrypted ciphertext using a key, and the same key is needed for decryption. Encryption securely protects data by allowing only authorized parties with the key to access it. Common encryption methods include DES, RSA, AES, Blowfish and Twofish. Free encryption tools include Veracrypt, Bitlocker and AxCrypt.

1. It’s your data – are you sure it’s safe?

2.  Data is any type of stored digital information
 Every company needs places to store
institutional knowledge and data.
 Frequently that data contains proprietary
information
 Personally Identifiable Data
 Employee HR Data
 Financial Data
 The security and confidentiality of this data
is of critical importance.

3.  Data needs to be available at all necessary
times
 Data needs to be available to only the
appropriate users
 Need to be able to track who has access to
and who has accessed what data

4.  Security is about the protection of
assets.
 Prevention: measures taken to protect
your assets from being damaged.
 Detection: measures taken to allow you
to detect when an asset has been
damaged, how it was damaged and
who damaged it.
 Reaction: measures that allow you to
recover your assets.

5.  A security policy is a comprehensive
document that defines a companies’
methods for prevention, detection,
reaction, classification, accountability
of data security practices and
enforcement methods.
 It generally follows industry best
practices as defined by ISO
17799,27001-02, PCI, ITIL, SAS-70,
HIPPA , SOX or a mix of them.
Security Policy

6.  The security policy is the key document in
effective security practices.
 Once it has been defined it must be
implemented and modified and include any
exceptions that may need to be in place for
business continuity.
 All users need to be trained on these best
practices with continuing education at
regular intervals.

7.  Data needs to be classified in the security
policy according to its sensitivity.
 Once this has taken place, the most sensitive
data has extra measures in place to
safeguard and ensure its integrity and
availability.
 All access to this sensitive data must be
logged.
 Secure data is usually isolated from other
stored data.

8.  Controlling physical access to the data
center or area where the data is stored.
 Active or Open Directory is a centralized
authentication management system that is
available to companies to control and log
access to any data on the system.
 Encryption of the sensitive data is critical
before transmission across public networks

9.  The use of firewalls on all publicly facing
WAN connections.
 Deploying VLANs’ and ACLs’ to isolate
sensitive departments from the rest of the
network.
 Shutting down unused switch ports.
 If wireless is deployed, use authentication
servers to verify and log the identity of those
logging on.
 Anti-Virus and malicious software protection
on all systems.

10.  There are four key issues in the security of
databases just as with all security systems
 Availability
 Authenticity
 Integrity
 Confidentiality

11.  Data needs to be available at all necessary
times
 Data needs to be available to only the
appropriate users
 Need to be able to track who has access to
and who has accessed what data

12.  . Need to ensure that the data has been
edited by an authorized source
 Need to confirm that users accessing the
system are who they say they are
 Need to verify that all report requests are
from authorized users
 Need to verify that any outbound data is
going to the expected receiver

13.  . Need to verify that any external data has
the correct formatting and other metadata
 Need to verify that all input data is accurate
and verifiable
 Need to ensure that data is following the
correct work flow rules for your
institution/corporation
 Need to be able to report on all data changes
and who authored them to ensure
compliance with corporate rules and privacy
laws.

14.  . Need to ensure that confidential data is
only available to correct people
 Need to ensure that entire database is
security from external and internal system
breaches
 Need to provide for reporting on who has
accessed what data and what they have done
with it
 Mission critical and Legal sensitive data must
be highly security at the potential risk of lost
business and litigation

15. DATA SECURITY - PASSWORD
Password protection is a security process that protects information
accessible via computers that needs to be protected from certain
users. Password protection allows only those with an
authorized password to gain access to certain information.
A strong password consists of at least six characters (and the more
characters, thestronger the password) that are a combination of letters,
numbers and symbols (@, #, $, %, etc.) if allowed. Passwords are typically
case-sensitive, so a strong password contains letters in both uppercase and
lowercase.

 PASSWORD
 PIN
 PICTURE
Nine-character passwords take five days to break, 10-character words
take four months, and 11-character passwords take 10 years. Make it up to 12
characters, and you're looking at 200 years' worth of security – not bad for
one little letter.

17. Encryption is the process of translating plain text data (plaintext)
into something that appears to be random and meaningless
(ciphertext). ... A symmetric key is used during both the encryption
and decryption processes. To decrypt a particular piece of
ciphertext, the key that was used to encrypt the data must be used.

18. Encryption is important because it allows you to securely protect
data that you don't want anyone else to have access.
Types of encryption:-
DES
RSA
AES
BLOWISH
TWOFISH
There are quite a few free tools that will allow to encrypt whole
text documents. Veracrypt, Bitlocker, AxCrypt.
