Network security refers to the set of methods, techniques, and technologies that an organization uses to secure its computer network infrastructure from unauthorized access, misuse, modification, or destruction. It is crucial because it protects sensitive and confidential data, prevents network downtime, and ensures business continuity by mitigating cyber threats, attacks, and vulnerabilities.

The four main elements of network security are application security, information security, network security, and operational security. Application security ensures the protection of applications and software from threats. Information security deals with securing confidential and sensitive data. Network security aims to protect the network infrastructure and devices from unauthorized access. Operational security ensures that the security protocols and procedures are followed correctly to mitigate cyber threats.

Recent threats to network security include malware, phishing, ransomware, and social engineering attacks. These threats are continuously evolving and becoming more sophisticated. Attackers are using advanced techniques to bypass security measures and exploit vulnerabilities.

Organizations can prevent network security threats by implementing security best practices, such as using strong passwords, regularly updating software and hardware, deploying anti-malware and anti-virus software, and providing regular security awareness training to employees. Additionally, using multi-factor authentication, implementing access control measures, and conducting regular vulnerability assessments can also help prevent network security threats.

The benefits of deploying a network security model in an organization include protecting sensitive data and intellectual property, mitigating cyber risks and threats, ensuring business continuity, and enhancing customer trust and confidence. A robust network security model can also help the organization comply with regulatory requirements and reduce financial losses due to cyber attacks.

Product details

Cyber ​​security refers to the body of technologies, processes, and practices designed to protect networks, devices, programs, and data from attack, damage, or unauthorized access. Cyber ​​security may also be referred to as information technology security. Cyber ​​security is important because government, military, corporate, financial, and medical organizations collect, process, and store unprecedented amounts of data on computers and other devices. A significant portion of that data can be sensitive information, whether that be intellectual property, financial data, personal information, or other types of data for which unauthorized access or exposure could have negative consequences. Organizations transmit sensitive data across networks and to other devices in the course of doing businesses, and cyber security describes the discipline dedicated to protecting that information and the systems used to process or store it. For an effective cyber security, an organization needs to coordinate its efforts throughout its entire information system. Elements of cyber encompass all of the following – network security, application security, endpoint security, data security, protecting company and customer information, identity management, database and infrastructure security, cloud security, mobile security. The most difficult challenge in cyber security is the ever-evolving nature of security risks themselves. Traditionally, organizations and the government have focused most of their cyber security resources on perimeter security to protect only their most crucial system components and defend against known treats. Today, this approach is insufficient, as the threats advance and change more quickly than organizations can keep up with. As a result, advisory organizations promote more proactive and adaptive approaches to cyber security. Following a cyber risk assessment, develop and implement a plan to mitigate cyber risk. This plan should encompass both the processes and technologies required to build a mature cyber security program. An ever-evolving field, cyber security best practices must evolve to accommodate the increasingly sophisticated attacks carried out by attackers. Combining sound cyber security measures with an educated and security-minded employee base provides the best defense against cyber criminals. While it may seem like a daunting task, start small and focus on your most sensitive data, scaling your efforts as your cyber program matures.

Cyber ​​Security template is intended primarily for companies providing data protection services. You can use the slides from this template when preparing a presentation of your services for a client. For example, you can describe the main areas of data protection that your company provides. Also, the slides of this template will be useful for startups when preparing a description of the data protection process in a new software product. The slides from this template can be used by educators in their data protection courses. All slides in the template are made in a cool color scheme and have modern infographics. If necessary, you can change the slides to suit your corporate style. Cyber ​​Security template will be a worthy addition to your collection of professional presentations.

Network and System Security Introduction CSE 5349/7349

Information Security • Computer security • Protect system resources • Protect data (dynamic/stored) • Network security • Protect network resources • Protect exchanged data Security = confidentiality + integrity + availability + authenticity CSE 5349/7349

Attacks • Passive attacks • Affects data confidentiality • More difficult to detect, less harmful • Active attacks • Affects data confidentiality, integrity, and/or availability • Easier detection, more harmful CSE 5349/7349

Attacks (cont’d) • Interruption • Interception • Modification • Fabrication CSE 5349/7349

Interruption • An asset of the system is destroyed of becomes unavailable or unusable • Attack on availability • Destruction of hardware • Cutting of a communication line • Disabling the file management system CSE 5349/7349

Interception • An unauthorized party gains access to an asset • Attack on confidentiality • Wiretapping to capture data in a network • Illicit copying of files or programs CSE 5349/7349

Modification • An unauthorized party not only gains access but tampers with an asset • Attack on integrity • Change values in a data file • Alter a program to make it perform differently • Modify content of messages transmitted on a network CSE 5349/7349

Fabrication • Unauthorized party inserts counterfeit objects into the system • Attack on authenticity • Insertion of spurious messages in a network • Addition of records to a file CSE 5349/7349

Network Security Services • Authentication • validate authenticity claims (identity/data) • Authorization • Enforce selective access (information/resources) • Confidentiality • Prevent disclosure of data (entire message/selected fields/traffic characteristics) • Integrity • Prevent tampering of data (entire message/selected fields) • Non-repudiation • Proof of origin, proof of delivery CIA CSE 5349/7349

Security Mechanisms • Specific mechanisms • Access control list - resource protection • Encryption – data confidentiality • Digital signature – origin verification, non-repudiation • Notarization – trusted third party assurance • Traffic padding – traffic characteristic confidentiality • Routing control – flow protection CSE 5349/7349

Mechanisms (cont’d) • Pervasive mechanisms • Event detection • Security audit trail • Security recovery CSE 5349/7349

Password Security CSE 5349/7349

System Security • Two issues • Attack by unauthorized users • Attack by authorized users • Solution • Unauthorized – authenticate • Authorized – access control CSE 5349/7349

Authentication • Usual User ID + passwd • ID public, passwd private • When to authenticate • Beginning of session • Periodically within session • After a pause • Beginning of sensitive operation CSE 5349/7349

Selection of Passwd • Psychological issues • Disclosing passwd – social engineering • Difficulty in entering • Difficulty in remembering • System issues • Targeted and general attacks • Multi-lateral security • User training CSE 5349/7349

Attacks on Passwd • Attack on passwd entry • Interface design • Eavesdropping • Trusted path (ex. Ctrl-Alt-Del) • Passwd retry counters • Timing attack • Attack on smart cards • Attack on passwd storage • Audit trail • Need for one-way encryption CSE 5349/7349

Passwd Cracking • Brute force attack • Use all combination of characters • Knowledge of victim • Names, license plate numbers… • Dictionary attack CSE 5349/7349

Defense • Use different passwds for users/systems • No default passwds • Against brute force • Longer passwds • More than letters and numbers • Case sensitive • Against dictionary • No words • No “obvious” passwds CSE 5349/7349

System Defenses • Run passwd filters to weed out weak ones • Generate random passwds for users • Enforce passwd life-time • Limit failed logins • Notifying history to users CSE 5349/7349

Salting the Passwd • What happens if two users choose the same passwd? • Will result in same hash • Add some random information (salt)to the passwd before hashing • Makes it harder to crack CSE 5349/7349

Access Control CSE 5349/7349

Authentication vs. Access Control • Authentication about who you are • Access control – who may do what to what? • Major portion of security breaches organized by authorized users CSE 5349/7349

Control Structures • Formalism • Subjects, Objects, Access permissions • Access control matrix • Example CSE 5349/7349

Capabilities and Access Control Lists (ACL) • For large systems • Large number of subjects and objects • Control matrix very large and sparse • Store the matrix rows and columns as linked lists • Rows – capabilities • Columns - ACLs CSE 5349/7349

Capabilities • What subject A is allowed to do • Whenever a new object is created, other subjects may be given the capabilities to access it CSE 5349/7349

Intermediate Solutions • Group permissions • Negative permissions • Protection rings • Permission trees CSE 5349/7349

Group Permissions • Place number of users in a named group • ACLs for groups CSE 5349/7349

Negative Permission • To exclude specific permission from the group grant CSE 5349/7349

Protection Rings • Assigning priority levels to objects and subjects • 0 kernel • 1 OS • 2 system utilities • 3 other programs • Access decisions based on comparing the levels of Ss and Os. CSE 5349/7349

Hardware Protection • Protection problem • Preventing one processor from interfering with another • Confinement problem • Preventing programs communicate outside the authorized channels • Memory management • Reference monitor CSE 5349/7349

Security Processors • Pentium 3 processor serial number • ARM (Acorn Risc Machine) • Smart cards • Protection of protection hardware • Tamper resistance CSE 5349/7349

Attack (cont’d) • Smashing the stack • Finger bug in UNIX • Does not check the length of the input string • Trailing edge could be used to overwrite the system stack • Want to be a root user? CSE 5349/7349

Cryptography CSE 5349/7349

Terminology • Cryptography • Cryptanalysis • Cryptology • Plain text • Cipher text CSE 5349/7349

Historical Background • Mono-alphabetic substitution • Caesar cipher • Stream ciphers C= P + K mod 26 • One-time pad • Perfect secrecy (Shannon’s theorem) • No integrity • Block codes • Playfair • One-way functions CSE 5349/7349

Formal Classifications • Type of operation • Substitution • Transposition • Number of keys used • Symmetric (one key, private) • Asymmetric (two keys, public) • Mode of plain text processing • Block vs. stream CSE 5349/7349

Cryptanalysis • Attacks • Known plain text attack • Chosen plain text • Chosen cipher text • Security • Unconditionally secure • Computationally secure CSE 5349/7349

Block Ciphers • Block of plain text converted into block of cipher of equal length • Based on Fiestal block structure • Unique transformation • Reversible • Example • Small blocks vulnerable to attacks • Large blocks impractical to implement CSE 5349/7349

Fiestal Cipher (FC) • Based on product ciphers • Alternate substitutions and permutations • Shannon’s proposal • Diffusion • Dissipate plain text statistics into long-range cipher statistics • Example: Averaging operation on characters • A permutation on binary bits followed by some operations • Confusion • To make the deduction of the key difficult CSE 5349/7349

FC Structure • Multiple rounds • Round function (based on the round key) • Substitution (XOR) • Permutation (Exchange of halves) • Parameters • Block size (64 bits) • Key size (128 bits) • Number of rounds (16) • Sub-key generation algorithm • Round function CSE 5349/7349

Plaintext Plaintext Encrypt with Decrypt with secret key secret key Ciphertext DES CSE 5349/7349

DES • Currently the most widely used block cipher in the world • IBM’s LUCIFER was the precursor • One of the largest users of the DES is the banking industry, particularly with EFT • Although the standard is public, the design criteria used are classified CSE 5349/7349

DES Security • Recent analysis has shown that DES is well designed (diffusion & confusion) • Rapid advances in computing speed though have rendered the 56 bit key susceptible to exhaustive key search • 1997 on a large network of computers in a few months • 1998 on dedicated h/w in a few days • 1999 above combined in 22hrs! • DES also theoretically broken using Differential or Linear Cryptanalysis • In practice, unlikely to be a problem yet CSE 5349/7349

Overview of DES Encryption • Basic process consists of: • An initial permutation (IP) • 16 rounds of a complex key dependent calculation F • A final permutation, being the inverse of IP CSE 5349/7349

Initial permutation Round 1 L R i – 1 i – 1 Round 2 K F 56-bit i key … + Round 16 L R i i Final permutation • Each Round • 64-bit key (56-bits + 8-bit parity) • 16 rounds CSE 5349/7349

Initial Permutation • No improvement in security, cipher gets more complex 58, 50, 42, 34, 26, 18, 10, 2, 60, 52, 44, 36, 28, 20, 12, 4, 62, 54, 46, 38, 30, 22, 14, 6, 57, 49, 41, 33, 25, 17, 9, 1, 59, 51, 43, 35, 27, 19, 11, 3, 61, 53, 45, 37, 29, 21, 13, 5, 63, 55, 47, 39, 31, 23, 15, 7 CSE 5349/7349

DES Key Generation • Sub-keys used in each round are formed by • An initial permutation of the key (PC1) which selects 56-bits in two 28-bit halves • 16 stages consisting of: • selecting 24-bits from each half • permuting them by PC2 for use in function f, • rotating each half separately either 1 or 2 places depending on the key rotation schedule KS • Can be described functionally as: SKi = PC2(KS(PC1(Key),i)) CSE 5349/7349

Expansion Function E • Expands RH side data input from 32 to 48 bits by duplicating some bits • Specifically split input into 8 groups of 4 bits • Duplicate bits from either side to form groups of 6 bits CSE 5349/7349

Substitution (S) Boxes • 8 S-boxes, each of which maps 6 bits to 4 bits • Each S-box is actually 4 little 4 bit boxes • Outer bits 1 & 6 (row bits) select one of the 4 rows • Inner bits 2-5 (col bits) are substituted for 4 others CSE 5349/7349

DES Decryption • To decrypt a block of data must unwind all steps of data computation • With Feistel design, same as just doing encryption steps again • Except that must use subkeys in reverse order (SK16 first, then SK15 etc.) CSE 5349/7349

Network Video Recorder | Security System Singapore

Network Video Recorder or NVR is a software program that is a solution to an easier recording. The NVR converts video into digital formats to store in your disk drive or on memory slot. It does not capture video itself, but is connected to a hardware dedicated for the purpose of video capturing. It is most commonly connected with the IP video surveillance system. This is a unique method to safely store your data on the system and you can see your happening from your computer or a device far from the original location where the camera is placed.
