Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

2. UNIT III E-COMMERCE SECURITY AND
PAYMENT SYSTEMS
E-Commerce Security Environment – Security
threats in E-Commerce – Technology Solutions:
Encryption, Securing Channels of
Communication, Protecting Networks, Protecting
Servers and Clients – Management Policies,
Business Procedure and Public Laws - Payment
Systems
3. Securing Channels of Communication
Secure Sockets Layer (SSL) and Transport Layer
Security (TLS):
When you receive a message from a server on the
Web with which you will be communicating through a
secure channel, this means you will be using SSL/TLS
to establish a secure negotiated session.
The URL changes from HTTP to HTTPS.
4. Securing Channels of Communication
Secure Sockets Layer (SSL) and Transport
Layer Security (TLS):
A secure negotiated session is a client-server
session in which the URL of the requested
document, along with the contents, contents of
forms, and the cookies exchanged, are encrypted.
6. Securing Channels of Communication
Secure Sockets Layer (SSL) and Transport Layer Security
(TLS):
For instance, your credit card number that you entered into a
form would be encrypted.
Through a series of handshakes and communications, the
browser and the server establish one another’s identity by
exchanging digital certificates, decide on the strongest shared
form of encryption, and then proceed to communicate using an
agreed upon session key.
7. Securing Channels of Communication
Secure Sockets Layer (SSL) and Transport Layer
Security (TLS):
A session key is a unique symmetric encryption key
chosen just for this single secure session. Once used, it is
gone forever.
SSL/TLS provides data encryption, server authentication,
optional client authentication, and message integrity for
TCP/IP connections.
8. Securing Channels of Communication
Secure Sockets Layer (SSL) and Transport Layer
Security (TLS):
SSL/TLS addresses the issue of authenticity by
allowing users to verify another user’s identity or the
identity of a server.
It also protects the integrity of the messages
exchanged.
9. Securing Channels of Communication
Virtual Private Networks (VPNs):
A virtual private network (VPN) allows remote users to
securely access a corporation’s local area network via the
Internet, using a variety of VPN protocols.
VPNs use both authentication and encryption to secure
information from unauthorized persons.
Authentication prevents spoofing and misrepresentation of
identities.
10. Securing Channels of Communication
Virtual Private Networks (VPNs):
A remote user can connect to a remote private local network using a
local ISP.
The VPN protocols will establish the link from the client to the
corporate network as if the user had dialed into the corporate network
directly.
The process of connecting one protocol through another (IP) is called
tunneling, because the VPN creates a private connection by adding an
invisible wrapper around a message to hide its content.
11. Securing Channels of Communication
Virtual Private Networks (VPNs):
The primary use of VPNs is to establish secure
communications among business partners—larger
suppliers or customers, and employees working
remotely.
Using the Internet and VPN as the connection method
significantly reduces the cost of secure
communications.
12. Securing Channels of Communication
Wireless (Wi-Fi) Networks:
Early Wi-Fi networks used a security standard called
Wired Equivalent Privacy (WEP) to encrypt information.
WEP was very weak, and easy for hackers to crack.
A new standard, Wi-Fi Protected Access (WPA), was
developed that provided a higher standard of protection, but
this too soon became vulnerable to intrusion.
13. Protecting Networks
Firewalls and proxy servers are intended to build
a wall around your network and the attached
servers and clients, just like physical-world
firewalls protect you from fires for a limited
period of time.
Firewalls and proxy servers share some similar
functions, but they are quite different.
14. Protecting Networks
Firewalls:
A firewall refers to either hardware or software that filters
communication packets and prevents some packets from
entering or exiting the network based on a security policy.
The firewall controls traffic to and from servers and
clients, forbidding communications from untrustworthy
sources, and allowing other communications from trusted
sources to proceed.
15. Protecting Networks
Firewalls:
Every message that is to be sent or received from the network is
processed by the firewall, which determines if the message
meets security guidelines established by the business.
Firewalls can filter traffic based on packet attributes such as
source IP address, destination port or IP address, type of service
(such as WWW or HTTP), the domain name of the source, and
many other dimensions.
16. Protecting Networks
Firewalls:
The increasing use of firewalls by home and business
Internet users has greatly reduced the effectiveness of
attacks, and forced hackers to focus more on e-mail
attachments to distribute worms and viruses.
There are two major methods firewalls use to validate
traffic: packet filters and application gateways
17. Protecting Networks
Firewalls:
Packet filters examine data packets to determine
whether they are destined for a prohibited port or
originate from a prohibited IP address.
The filter specifically looks at the source and
destination information, as well as the port and packet
type, when determining whether the information may
be transmitted.
18. Protecting Networks
Firewalls:
Application gateways are a type of firewall that filters
communications based on the application being
requested, rather than the source or destination of the
message.
Such firewalls also process requests at the application
level, farther away from the client computer than
packet filters.
19. Protecting Networks
Firewalls:
By providing a central filtering point, application gateways
provide greater security than packet filters but can compromise
system performance.
Next-generation firewalls use an application-centric approach to
firewall control.
They are able to identify applications regardless of the port,
protocol, or security evasion tools used; identify users regardless
of device or IP address
21. Protecting Networks
Proxy Servers:
Proxy servers (proxies) are software servers (often a dedicated
computer) that handle all communications originating from or
being sent to the Internet by local clients, acting as a
spokesperson or bodyguard for the organization.
Proxies act primarily to limit access of internal clients to
external Internet servers, although some proxy servers act as
firewalls as well.
22. Protecting Networks
Proxy Servers:
Proxy servers are sometimes called dual-home
systems because they have two network interfaces. To
internal computers, a proxy server is known as the
gateway, while to external computers it is known as a
mail server or numeric address.
When a user on an internal network requests a web
page, the request is routed first to the proxy server.
23. Protecting Networks
Proxy Servers:
The proxy server validates the user and the nature of the request,
and then sends the request onto the Internet.
A web page sent by an external Internet server first passes to the
proxy server. If acceptable, the web page passes onto the internal
network web server and then to the client desktop.
By prohibiting users from communicating directly with the
Internet, companies can restrict access to certain types of sites,
such as pornographic, auction, or stock-trading sites.
24. Protecting Networks
Intrusion Detection and Prevention Systems:
An intrusion detection system (IDS) examines
network traffic, watching to see if it matches certain
patterns or preconfigured rules indicative of an attack.
If it detects suspicious activity, the IDS will set off an
alarm alerting administrators and log the event in a
database.
25. Protecting Networks
Intrusion Detection and Prevention Systems:
An intrusion prevention system (IPS) has all the
functionality of an IDS, with the additional ability to
take steps to prevent and block suspicious activities.
An IPS can terminate a session and reset a connection,
block traffic from a suspicious IP address, or
reconfigure firewall or router security controls.
26. Protecting Servers and Clients
Operating System Security Enhancements:
The most obvious way to protect servers and clients is
to take advantage of automatic computer security
upgrades.
The Microsoft, Apple, and Linux/Unix operating
systems are continuously updated to patch
vulnerabilities discovered by hackers.
27. Protecting Servers and Clients
Operating System Security Enhancements:
These patches are autonomic; that is, when using these
operating systems on the Internet, you are prompted and
informed that operating system enhancements are available.
Users can easily download these security patches for free.
The most common known worms and viruses can be
prevented by simply keeping your server and client
operating systems and applications up to date.
28. Protecting Servers and Clients
Operating System Security Enhancements - Anti-Virus
Software:
The easiest and least-expensive way to prevent threats to
system integrity is to install anti-virus software.
Anti-virus programs can be set up so that e-mail
attachments are inspected before you click on them, and the
attachments are eliminated if they contain a known virus or
worm.
29. Protecting Servers and Clients
Operating System Security Enhancements - Anti-Virus
Software:
Anti-virus suite packages and stand-alone programs are
available to eliminate intruders such as bot programs,
adware, and other security risks.
Such programs work much like anti-virus software in that
they look for recognized hacker tools or signature actions
of known intruders.
