Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

2. Network
A network is a set of devices/nodes connected by
links for the purpose of data communication
Evaluation criteria for a network
Performance: Transit time, Response time, Throughput
Reliability: Frequency of failure, Recovery time
Security
5. The Internet
The Internet is a network of networks that consists of
numerous wide- and local- area networks joined by
connecting devices
Users who want internet connection today use the
services of Internet Service Providers
7. Protocol
A protocol is a system of digital rules governing data
communication between computers/other devices
Protocol specifies what is communicated, how and
when it is communicated
Key elements of a protocol are
Syntax: Refers to structure or format of the data being
sent
Semantics: Refers to the meaning of each section of bits
Timing: When data should be sent and how fast it can
be sent
8. Protocol Layers
Each layer of a protocol implements a service by:
Performing some actions itself
Using services provided by any of the lower layers
Advantages of Layering:
Complex task divided in smaller ones at various layers
Layer implementation can be changed without
affecting other layers
Different teams can develop h/w or s/w for different
layers
9. TCP/IP protocol suite
TCP/IP protocol - A hierarchical protocol made of
interactive modules, each providing specific functionality.
IP
SCTP TCP UDP
FTP HTTP SMTP

10. TCP/IP Model
•Provides Services to users e.g. email, chat, wwwApplication Layer
•Process-to-process message deliveryTransport Layer
•Routing
•Congestion ControlNetwork layer
•Provide raw transmission across a link
•Error detection and correction
•Flow control
Data Link Layer
•Transmits raw bits over communication channelPhysical Layer
11. Connection Establishment: TCP/IP
TCP uses control messages to manage the process of
contact and communication
Two control message types are used in connection
setup, which are specified by setting the following two
flags:
SYN: This bit indicates that the segment is being used to
initialize a connection. SYN stands for synchronize
ACK: This bit indicates that the device sending the segment
is conveying an acknowledgement for a message it has
received
14. Advantages of TCP
Is Reliable & provides Connection Oriented Service
Provides Flow Control
Implements Error Control mechanism
Provides congestion control
Is an industry standard, open protocol
Has a scalable architecture
15. VoIP
VoIP stands for Voice Over Internet Protocol
VoIP is a methodology and group of technologies that facilitate the transmission of
voice and data over standard protocol networks based on IP like Internet
Few other terms which are synonymous with VOIP are Internet Telephony, IP
Communications etc.
It converts the Analog voice and data signals from the sending end into digital form to
be transmitted over the internet and then converts the same into Analog signals at the
receiving end
Step for voice over IP transmission are
Signalling Channel Setup Digitization of Analog signals Encoding
17. VoIP: How it is different
Traditional Telephony VoIP
When you call using the Normal Phone:
Public Switched Telephone Network
(PSTN), you use circuit-switched
telephony.
VoIP, in contrast to PSTN, uses what is
called packet-switched telephony.
This system works by setting up a
dedicated channel (or circuit) between
two points for the duration of the call.
Using this system, the voice information
travels to its destination in countless
individual network packets across the
Internet.
These telephony systems are based on
copper wires carrying analog voice
data over the dedicated circuits.
VoIP systems don’t need dedicated
circuits. They use the infrastructure used
for providing internet connectivity.
18. VoIP: Advantages
Cost Effectiveness
• Routing phone calls over existing data networks to avoid the need for
separate voice and data networks
• VoIP calls cost much lesser
Operational Flexibility
• More than one telephone call over a single broadband connection
• Integration with other services Data file exchanges, Video
conferencing, Managing address books
• Location Independence. Only Internet connection is required
Editor's Notes
A number of tasks need to be performed by the protocol at both the sender’s and receiver’s end. Hence the protocol is divided into many layers.
Hierarchical protocol – Each upper layer protocol is supported by one or more lower level protocols.The TCP/IP protocol suite supports various protocols in each layerAt the physical and data link layers, it doesn’t define any specific protocolAt network layer, it supports Internetworking ProtocolAt Transport layer, it supports User Datagram Protocol, Stream Control Transmission Protocol, Transmission Control ProtocolAt Application Layer, many protocols are supported including File Transfer Protocol, Hyper Text Transfer Protocol, Simple Mail Transfer Protocol
TCP is a connection oriented protocol. Thus, before initiating data transfer, TCP establishes a dedicated albeit virtual pathway between the nodesTCP operates in full duplex mode i.e. two nodes are able to send data to each other simultaneously.The client sends the first message, a Syn message for synchronization of segment numbers The server sends a Syn+Ack message which serves two purposes : synchronization of segment nos. for communication in other direction and acknowledgement of the first Syn messageThe client sends the 3rd message which is just a Acknowledgement message. After this data transfer may begin between the two.
Similar to connection Establishment process
Numbering system of data packets allows byte oriented flow controlImplements Checksum mechanism for error controlUses buffers at both sender and receiver ends for congestion controlTCP/IP is not controlled by any one institue
