CyberThreats
5. Trojan Horse: A computer program that conceals
harmful code.ATrojan horse usually masquerades as
a useful program that a user would wish to execute.
Virus: A program that infects computer files, usually
executable programs, by inserting a copy of itself into
the file.These copies are usually executed when the
infected file is loaded into memory, allowing the virus
to affect other files. Unlike a computer worm, a virus
requires human involvement (usually unwitting) to
propagate.

Phishing:Using emails and websites designed to look
like those of legitimate businesses/government
agencies to deceive internet users into disclosing
personal data, e.g. bank and financial account
information and passwords.
DoS (Denial of Service): A method of attack from a
single source that denise system access to legitimate
users by overwhelming the target computer with
messages and blocking legitimate traffic. It can
prevent a system from being able to exchange data
with other systems of use the internet.
CyberThreats
7. Distributed Denial of Service (DDoS):A
variant of the DoS attack that uses a
coordinated attack from a distributed system
of computers rather than from a single source.
It often makes use of worms to spread to
multiple computers that can then attack the
target.

synchronizes and conducts
activities to:
Direct the operations and defense of
specified DoD information networks
Prepare to, and when directed,
conduct full spectrum military
cyberspace operations in order to
enable actions in all domains, ensure
US/Allied freedom of action in
cyberspace and deny the same to our
adversaries.
