Spear Phishing

• Spear phishing or identity theft is one of the
  most common security threats to any start up or
  established organization. Employees/users/managers
  typically receive an email asking for sensitive
  information like username and password. Since the
  email appears genuine to all employees at an
  organization, it is easy for fooling people and
  forcing them to give access to a companys entire
  security system. This makes it a major network
  security threat.

Unsecured Wireless Access Points

• Unless you have been living under a rock, it is
  likely that your business uses wireless devices
  daily for accessing the internet and local area
  network. While there is no harm in using wireless
  networking, it has also significantly increased
  the security risks to your network. If intruders
  are physically present within your office
  premises, they can connect to your network and
  release viruses, malware or attempt to hack your
  servers.

Malicious code

• Due to its ability of causing vulnerabilities in
  the system (like stolen passwords and deleted
  files) and secretly installing on computers,
  Malicious Code exists as one of the biggest
  network security threats to a business. According
  to Kaspersky Lab, hackers can steam employee and
  customer information to gain financially, as not
  all antivirus protection and protocols can block
  this threat.

5
USB and External Devices

• According to a research conducted by Security
  Research Labs in 2014, it was revealed that USBs
  and other external devices have the capability of
  being reprogrammed for stealing the contents of
  any PC. They can even pretend to be an active
  network card, gaining the ability of changing
  your computers domain name to redirect your
  traffic secretly (tracking all online and local
  area network searches).
