Tatort Internet: Edition 2022

1. 00:00Crime Scene Internet Attack Vectors and protective measures welcome
2. 00:05to our online course daily there are news on television in the newspapers
3. 00:12about new cyber attacks of very different kinds,
4. 00:16whole cities are taken off the grid Hospitals can no longer treat patients,
5. 00:22because all the medical data is encrypted.
6. 00:25Blackmailers want money for for the decryption with
7. 00:28Spam mail attacks is being worked in the Christmas mail will be charting software.
8. 00:36He hides, so many problems with this meanwhile nevertheless
9. 00:42fundamental infrastructure of our infrastructure of our digital world,
10. 00:46if you now want to understand understand,
11. 00:48what is actually going on? Why and how do such attacks work,
12. 00:54if they want to bring light into the darkness of the jungle about all this?
13. 01:00Terms that are mentioned in the cyber security context and very important,
14. 01:06if you want to protect yourself and be safer on the Internet,
15. 01:10then you are exactly right here with our course,
16. 01:13what we offer are.
17. 01:16Numerous as is always the case with these courses are short videos,
18. 01:19which are then followed by interactive quizzes and assignments,
19. 01:23where they can immediately check whether the details of the topic well.
20. 01:30understood and then the whole thing becomes interesting because of that,
21. 01:34that on the discussion platforms there is the possibility to learn with the others and
22. 01:39exchange own experiences with those of other learners in similar situations
23. 01:47and they can also get a certificate certificate for attending the course,
24. 01:53There are no entry requirements. entry requirement,
25. 01:56so everybody should be able to do it.
26. 02:00To deal, with a certain effort with these issues,
27. 02:03what we are introducing here and where we want to introduce them,
28. 02:07to know at the end,
29. 02:10so what we're encouraging them to do is deal with the
30. 02:15material to help understand in more detail,
31. 02:17how the digital world works,
32. 02:21where the points of attack are,
33. 02:23which weaknesses have to be must be overcome by one's own activities,
34. 02:28which systematic problems there are and in dealing with these
35. 02:36learning material you should progress noise regulation,
36. 02:42to see exactly where they stand and again the discussion forum that is very important with others
37. 02:51learners to exchange information about their experience of their experience,
38. 02:56if they have not understood exactly,
39. 02:58when they see things differently. That they have the possibility with
40. 03:02with others and to with us about it,
41. 03:04what do we want to do in detail in our openhpi course Crime Scene Internet,
42. 03:12we want to give an introduction to this basic topic of internet security,
43. 03:15to do that we need to understand a bit understand how the internet works,
44. 03:18how the World Wide Web works,
45. 03:21how such applications are built and where the cybercriminals are able to attack,
46. 03:31which actors are on the on the Internet and which
47. 03:35dangers lurk there Laura I take on whole
48. 03:38different places and we want to then discuss them in more detail in the individual weeks,
49. 03:42so we're going to start in week two with the digital identities,
50. 03:47so if we use a service on the Internet Amazon account are set up,
51. 03:52where our activities are accumulated,
52. 03:55so online account over then pay and order processed.
53. 03:59And for this the application recognise us,
54. 04:03who we are in the network, how does what role do passwords play in this,
55. 04:09because that is the protection mechanism, which then protects our accounts from unauthorised use and
56. 04:16what are the problems around passwords in terms of cyber security,
57. 04:20then in the third week we want to address another complex,
58. 04:25which is very important in the cyber security on the Internet,
59. 04:33because that's treasure. Software malware that hackers use to grab unauthorised data,
60. 04:39with which hackers can influence certain things data and manipulate them,
61. 04:47so what are there different types of malware,
62. 04:52what attack vectors do they carry and how does this can this malware even open?
63. 04:59kidney computers, these are the the issues that we will be dealing with in the third
64. 05:03week will occupy the fourth
65. 05:06week will be about how information is transmitted via the Internet,
66. 05:10i.e. via the transport routes the internet as a network of networks
67. 05:14with quite different responsible for the
68. 05:17individual parts nice eat and secure network without own
69. 05:21Measures can information via the Internet
70. 05:25sent can be viewed by unauthorised or even manipulated,
71. 05:31so this is a subject we will in the fourth week,
72. 05:35why the internet is so insecure and how the widespread attacks work,
73. 05:41which right here on the transport routes,
74. 05:46the essential protective measure there are encryption encryption,
75. 05:50so, we can't prevent that the hackers can access data
76. 05:54transported over the Internet being transported over the internet,
77. 05:56but we can prevent those who have can understand,
78. 06:00that you can do that with the data from doing that, we can do that by
79. 06:03encryption prevent encryption,
80. 06:06that is the technique of cryptography which plays a big and that is the topic of week 5,
81. 06:12We want to look at the different methods and methods and we want to see,
82. 06:15what technical possibilities there are for our news
83. 06:20before they are transported over the insecure internet
84. 06:24Funsport ways to protect and then we are already
85. 06:29almost at the end but have to one more big block
86. 06:32address in the context of cybersecurity, namely privacy,
87. 06:38what about the privacy internet,
88. 06:40what are the risks of the digital world?
89. 06:43So, if you want to be reachable everywhere with your smartphone you want to be reachable everywhere,
90. 06:47then the corresponding mobile operator know exactly,
91. 06:51where they are at that second,
92. 06:53so that's information,
93. 06:56that is needed to use digital digital services can do that.
94. 07:00be misused, what does that look like,
95. 07:02if such data is then known,
96. 07:06what influence does on privacy,
97. 07:08how can I protect my privacy also be visible to others,
98. 07:15what movement is do on the internet?
99. 07:17So, these are the big Themes that will be discussed in the 6th session.
100. 07:20week will be addressed further course information,
101. 07:26we have now started with the bus on the 13th
102. 07:30May 2020 the course.
103. 07:34End will be after 6 weeks on the 24th.
104. 07:37June this year and the final examination will take place the following week,
105. 07:44you are free to decide when you have to take the time,
106. 07:47but then do it in one go,
107. 07:51if you want to deal with the want to deal with the course,
108. 07:54with what amount of work and time you have to depends, of course, on the form.
109. 07:59Education but the thorough occupation with the
110. 08:02learning materials and self-testing which we think prompts
111. 08:06per week employment from three to six hours of weekly homework,
112. 08:13these are important for Sat fikc because they have to be included in the
113. 08:17homework 50% of the score,
114. 08:20For this they then have 60 minutes every week
115. 08:25so and of course we can discuss everything in depth,
116. 08:28so I could recommend some some reading material here,
117. 08:34so e.g. Our book with Harald Sack on digital communication,
118. 08:40there is a lot of material to read more about the functionality of the internet,
119. 08:46how it all works,
120. 08:49can be found in the volume internetworking and decoupled questions of security
121. 08:56then in this small booklet Security and Trust.
122. 09:01Short introduction of the teaching team my name is Christoph I mean.
123. 09:05I am dean and director of the Hasso Plattner Institute.
124. 09:09Hold the chair for Internet Technologies and Systems and in our
125. 09:13research we concentrate on the topic of security on the one hand on the topic of security, which is why
126. 09:19also then the teaching team doctoral students work with me,
127. 09:26who are active in this subject. We are working on
128. 09:30chair but also with with digital learning.
129. 09:33developed these openhpi platforms and in this respect we are always very interested in a
130. 09:42such learning happen and also to measure the learning progress,
131. 09:46these are my capable companions and supporters Erik Klima Alexander Mühle,
132. 09:53Chapel Daniel Köhler everything PhD students in the field of security,
133. 09:57this one in the kiss. Who created the course together with me,
134. 10:04who developed the questions set the examination questions and who
135. 10:09in the discussion forums then also in the discussion forums and give their opinion and
136. 10:17help and with them vigorous discussion.
137. 10:21They will also individually get to know each other at various
138. 10:24securitisation videos on many a topic,
139. 10:27there is another digression, that is interesting for the interested
140. 10:31who then really want to know more about about this subject,
141. 10:35that is perhaps not so necessary for the overall understanding.
142. 10:40So, we are now looking forward to the start of our openhpi course crime scene internet attack vectors
143. 10:49and protective measures a lot of fun and many new experiences and insights.
