የሳይበር አጥቂ ዓይነቶች(Types of Cyber Attackers)

የሳይበር አጥቂ ዓይነቶች

በኮምፒተር እና በኮምፒተር አውታረመረቦች ውስጥ አጥቂ ማለት አንድን ንብረት ለማጥፋት ያልተፈቀደ መዳረሻን ለማጥፋት ፣ ለማጋለጥ ፣ ለመለወጥ ፣ ለማሰናከል ፣ ለመስረቅ ወይም ያልተፈቀደ መዳረሻን ለማግኘት ወይም አደገኛ ተግባራትን የሚያከናውን ግለሰብ ወይም ድርጅት ነው ፡፡

የበይነመረብ መዳረሻ በዓለም ዙሪያ በሰፊው እየሰፋ ሲሄድ ፣ እና እያንዳንዳችን በድር ላይ ብዙ ጊዜ የምናጠፋ እንደመሆኑ መጠን አጥቂም እያደገ ነው ፡፡ አጥቂዎች ያልተፈቀደ መዳረሻን ለማግኘት ሊሞክሩን እና ሊያጠቁን የሚሞክሩትን እያንዳንዱን መሳሪያ እና ዘዴ ይጠቀማሉ ፡፡

ከዚህ በታች የተገለጹት አራት ዓይነት አጥቂዎች አሉ-


1. የሳይበር ወንጀለኞች

የሳይበር ወንጀለኞች ጥንቃቄ የተሞላበት የኩባንያ መረጃን ወይም የግል መረጃን ለመስረቅ እና ትርፍ ለማምጣት በማሰብ ቴክኖሎጂን በሳይበር ወንጀል ለመፈፀም ቴክኖሎጂን የሚጠቀሙ ግለሰብ ወይም ቡድን ናቸው ፡፡ በዛሬው ጊዜ እነሱ በጣም ታዋቂ እና በጣም ንቁ የአጥቂ ዓይነቶች ናቸው ፡፡

የሳይበር ወንጀለኞች የሳይበር ወንጀሎችን ለመስራት በሦስት ሰፊ መንገዶች ኮምፒውተሮችን ይጠቀማሉ-


እንደ ዒላማቸው ኮምፒተርን ይይመርጣሉ - በዚህ ውስጥ እንደ ቫይረሶችን ማሰራጨት ፣ የመረጃ ስርቆት ፣ የማንነት ስርቆት ፣ ወዘተ ያሉ የሳይበር ወንጀሎችን ለማድረግ የሌሎችን ኮምፒውተሮችን ያጠቃሉ ፡፡

ኮምፒተርን እንደ መሣሪያቸው ይጠቀማሉ - በዚህ ውስጥ ኮምፒተርን እንደ አይፈለጌ መልእክት ፣ ማጭበርበር ፣ ሕገወጥ ቁማር ፣ ወዘተ ያሉ የተለመዱ ወንጀሎችን ለማድረግ ይጠቀማሉ ፡፡

ኮምፒተርን እንደ መለዋወጫቸው ይጠቀማሉ- በዚህ ውስጥ ኮምፒተርን በሕገ-ወጥነት መረጃን ለመስረቅ ይጠቀማሉ ፡፡


2. ሃክቲቪስቶች

ሃክቲቪስቶች የፖለቲካ አጀንዳዎችን ፣ ሃይማኖታዊ እምነቶችን ወይም ማህበራዊ ርዕዮተ-ዓለምን ለማሳደግ ተንኮል-አዘል እንቅስቃሴ የሚያካሂዱ ግለሰቦች ወይም የጠላፊዎች ቡድን ናቸው ፡፡ ከክልሎች ጋር አብሮ የሚሠራ የብሔራዊ ደህንነት ማሠልጠኛ የፀጥታ ሜንቶር ዋና የፀጥታ ባለሥልጣን ዳን ሎርማን እንደሚሉት “ሃክቲቪዝም ዲጂታል አለመታዘዝ ነው ፣ ለዓላማ ጠለፋ ነው” ብለዋል ፡፡ ሃክቲቪስቶች ለገንዘብ መረጃን ለመስረቅ የኮምፒተር ኔትወርክን እንደሚጠለፉ የሳይበር ወንጀለኞች አይደሉም ፡፡ እነሱ አብረው የሚሰሩ ግለሰቦች እና የጠላፊዎች ቡድን ናቸው እናም ኢ-ፍትሃዊነትን እንደሚዋጉ እራሳቸውን ይመለከታሉ።


3.መንግስት የተደገፈ አጥቂ

በመንግስት የሚደገፉ አጥቂዎች ከትውልድ አገራቸው የፖለቲካ ፣ የንግድ ወይም ወታደራዊ ፍላጎቶች ጋር የሚጣጣሙ ልዩ ዓላማዎች አሏቸው ፡፡ የዚህ አይነት አጥቂዎች በችኮላ አይደሉም ፡፡ የመንግስት ድርጅቶች ከፍተኛ ችሎታ ያላቸው ጠላፊዎች አሏቸው እና ቀዳዳዎቹ ከመጥፋታቸው በፊት ተጋላጭነቶችን በመለየት እነዚህን በመበዝበዝ የተካኑ ናቸው ፡፡ በእጃቸው ባሉት ሰፊ ሀብቶች ምክንያት እነዚህን አጥቂዎች ማሸነፍ በጣም ፈታኝ ነው ፡፡


4.የውስጥ ማስፈራሪያዎች 

የውስጥ ስጋት ለድርጅት ደህንነት ወይም ከውስጥ ለሚመጣ መረጃ ስጋት ነው ፡፡ የዚህ ዓይነቱ ስጋት ብዙውን ጊዜ የሚከሰቱት ከሠራተኞች ወይም ከቀድሞ ሠራተኞች ነው ፣ ግን ከሶስተኛ ወገኖች ፣ ተቋራጮችን ፣ ጊዜያዊ ሠራተኞችን ፣ ሠራተኞችን ወይም ደንበኞችን ጨምሮ ሊነሱ ይችላሉ ፡፡
የውስጥ ማስፈራሪያዎች ከዚህ በታች ሊመደቡ ይችላሉ-

ተንኮል-አዘል

ተንኮል-አዘል ዛቻዎች አንድ የውስጥ ሰው የድርጅቱን መረጃ ፣ ስርዓቶችን ወይም የአይቲ መሠረተ ልማቶችን ለመድረስ እና ለመጉዳት ሙከራዎች ናቸው ፡፡ እነዚህ የውስጥ አዋቂዎች ማስፈራሪያዎች ብዙውን ጊዜ እርካታው ባልነበራቸው ሰራተኞች ወይም የቀድሞ ሰራተኞች ድርጅቱ በሆነ መንገድ በእነሱ ላይ መጥፎ ነገር እየፈፀመ ነው ብለው ስለሚያምኑ እና በቀልን ለመጠየቅ ትክክለኛ እንደሆኑ ይሰማቸዋል ፡፡

የውስጥ ሰዎች እንዲሁ በገንዘብ ማበረታቻዎች ወይም በመበዝበዝ በተንኮል በውጭ ሰዎች ሲሸሸጉ ማስፈራሪያዎች ሊሆኑ ይችላሉ ፡፡


በአጋጣሚ

ድንገተኛ አደጋዎች በድንገት በውስጥ ሰራተኞች የሚሰሩ ማስፈራሪያዎች ናቸው ፡፡ በእንደዚህ ዓይነት ማስፈራሪያዎች ውስጥ አንድ ሰራተኛ በድንገት አስፈላጊ ፋይልን ይሰርዛል ወይም ሳያስበው ከኩባንያው ፖሊሲ ወይም የሕግ መስፈርቶች ባሻገር ለንግድ አጋርዎ ሚስጥራዊ መረጃን ያጋራል ፡፡


ቸልተኛ

እነዚህ ሰራተኞች የመጨረሻ ነጥቦችን እና ጠቃሚ መረጃዎችን ለመጠበቅ የተቀመጠ የድርጅትን ፖሊሲዎች ለማስወገድ የሚሞክሩባቸው ዛቻዎች ናቸው ፡፡ ለምሳሌ ፣ ድርጅቱ ለውጫዊ ፋይል መጋሪያ ጥብቅ ፖሊሲዎች ካለው ፣ ሰራተኞች በቤት ውስጥ መሥራት እንዲችሉ በህዝብ ደመና መተግበሪያዎች ላይ ስራን ለማጋራት ሊሞክሩ ይችላሉ። በእነዚህ ድርጊቶች ላይ ምንም ስህተት የለም ፣ ግን ምንም እንኳን ለአደጋ ስጋቶች ሊከፍቱ ይችላሉ ፡፡

Types of Cyber Attackers

In computer and computer networks, an attacker is the individual or organization who performs the malicious activities to destroy, expose, alter, disable, steal or gain unauthorized access to or make unauthorized use of an asset.

As the Internet access becomes more pervasive across the world, and each of us spends more time on the web, there is also an attacker grows as well. Attackers use every tools and techniques they would try and attack us to get unauthorized access.


There are four types of attackers which are described below-

1.Cyber Criminals

Cybercriminals are individual or group of people who use technology to commit cybercrime with the intention of stealing sensitive company information or personal data and generating profits. In today's, they are the most prominent and most active type of attacker.

Cybercriminals use computers in three broad ways to do cybercrimes-


Select computer as their target- In this, they attack other people's computers to do cybercrime, such as spreading viruses, data theft, identity theft, etc.

Uses the computer as their weapon- In this, they use the computer to do conventional crime such as spam, fraud, illegal gambling, etc.

Uses the computer as their accessory- In this, they

Security Technologies

With the rapid growth in the Internet, cybersecurity has become a major concern to organizations throughout the world. The fact that the information and tools & technologies needed to penetrate the security of corporate organization networks are widely available has increased that security concern.

Today, the fundamental problem is that much of the security technology aims to keep the attacker out, and when that fails, the defences have failed. Every organization who uses internet needed security technologies to cover the three primary control types - preventive, detective, and corrective as well as provide auditing and reporting. Most security is based on one of these types of things: something we have (like a key or an ID card), something we know (like a PIN or a password), or something we are (like a fingerprint). 

Some of the important security technologies used in the cybersecurity are described below-


Firewall

Firewall is a computer network security system designed to prevent unauthorized access to or from a private network. It can be implemented as hardware, software, or a combination of both. Firewalls are used to prevent unauthorized Internet users from accessing private networks connected to the Internet. All messages are entering or leaving the intranet pass through the firewall. The firewall examines each message and blocks those that do not meet the specified security criteria.


Categories of Firewalls

Firewall can be categorised into the following types-


1. Processing mode:

The five processing modes that firewalls can be categorised are-


Packet filtering

Packet filtering firewalls examine header information of a data packets that come into a network. This firewall installed on TCP/IP network and determine whether to forward it to the next network connection or drop a packet based on the rules programmed in the firewall. It scans network data packets looking for a violation of the rules of the firewalls database. Most firewall often based on a combination of:


Internet Protocol (IP) source and destination address.

Direction (inbound or outbound).

Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) source and destination port requests.

Packet filtering firewalls can be categorized into three types-


1. Static filtering:

The system administrator set a rule for the firewall. These filtering rules governing how the firewall decides which packets are allowed and which are denied are developed and installed.


2. Dynamic filtering:

It allows the firewall to set some rules for itself, such as dropping packets from an address that is sending many bad packets.


3. Stateful inspection:

A stateful firewalls keep track of each network connection between internal and external systems using a state table.


Application gateways

It is a firewall proxy which frequently installed on a dedicated computer to provides network security. This proxy firewall acts as an intermediary between the requester and the protected device. This firewall proxy filters incoming node traffic to certain specifications that mean only transmitted network application data is filtered. Such network applications include FTP, Telnet, Real Time Streaming Protocol (RTSP), BitTorrent, etc.


Circuit gateways

A circuit-level gateway is a firewall that operates at the transport layer. It provides UDP and TCP connection security which means it can reassemble, examine or block all the packets in a TCP or UDP connection. It works between a transport layer and an application layers such as the session layer. Unlike application gateways, it monitors TCP data packet handshaking and session fulfilment of firewall rules and policies. It can also act as a Virtual Private Network (VPN) over the Internet by doing encryption from firewall to firewall.


MAC layer firewalls

This firewall is designed to operate at the media access control layer of the OSI network model. It is able to consider a specific host computer's identity in its filtering decisions. MAC address
